Vṛtrāsura rebuked both the demigods and the demoniac soldiers because the demons were running in fear of their lives and the demigods were killing them from behind. The actions of both were abominable. When a fight takes place, the opposing parties must be prepared to fight like heroes. A hero never runs from the field of battle. He always fights face to face, determined to gain victory or lay down his life in the fight. That is heroic. Killing an enemy from behind is also inglorious. When an enemy turns his back and runs in fear of his life, he should not be killed. This is the etiquette of military science.

Vṛtrāsura insulted the demoniac soldiers by comparing them to the stool of their mothers. Both stool and a cowardly son come from the abdomen of the mother, and Vṛtrāsura said that there is no difference between them. A similar comparison was given by Tulasī dāsa, who commented that a son and urine both come from the same channel. In other words, semen and urine both come from the genitals, but semen produces a child whereas urine produces nothing. Therefore if a child is neither a hero nor a devotee, he is not a son but urine. Similarly, Cāṇakya Paṇḍita also says:

“What is the use of a son who is neither glorious nor devoted to the Lord? Such a son is like a blind eye, which simply gives pain but cannot help one see.”

Rebuking the demigods, Vṛtrāsura challenged, “O demigods, if you are actually heroes, stand before me now and try to show your prowess. If you do not wish to fight, if you are afraid of losing your lives, I shall not kill you, for unlike you, I am not so evil minded as to kill persons who are neither heroic nor willing to fight. If you have faith in your heroism, please stand before me.”

Śrī Narottama dāsa Ṭhākura sings:

“I am the servant of the Six Gosvāmīs, and the dust of their lotus feet provides my five kinds of food.” A Vaiṣṇava always desires the dust of the lotus feet of previous ācāryas and Vaiṣṇavas. Vṛtrāsura was certain that he would be killed in the battle with Indra, because this was the desire of Lord Viṣṇu. He was prepared for death because he knew that after his death he was destined to return home, back to Godhead. This is a great destination, and it is achieved by the grace of a Vaiṣṇava. Chāḍiyā vaiṣṇava-sevā nistāra pāyeche kebā: no one has ever gone back to Godhead without being favored by a Vaiṣṇava. In this verse, therefore, we find the words manasvināṁ pāda-rajaḥ prapatsye: “I shall receive the dust of the lotus feet of great devotees.” The word manasvinām refers to great devotees who always think of Kṛṣṇa. They are always peaceful, thinking of Kṛṣṇa, and therefore they are called dhīra. The best example of such a devotee is Nārada Muni. If one receives the dust of the lotus feet of a manasvī, a great devotee, he certainly returns home, back to Godhead.

When King Indra threw his club at Vṛtrāsura, Vṛtrāsura caught it in his left hand and retaliated by using it to strike the head of Indra’s elephant. Thus Indra’s attack was a disastrous failure. Indeed, Indra’s elephant was injured and thrown back fourteen yards. Therefore even though Indra stood with the thunderbolt to hurl against Vṛtrāsura, he was doubtful, thinking that the thunderbolt might also fail. Vṛtrāsura, however, being a Vaiṣṇava, assured Indra that the thunderbolt would not fail, for Vṛtrāsura knew that it had been prepared in accordance with the instructions of Lord Viṣṇu. Although Indra had doubts because he could not understand that Lord Viṣṇu’s order never fails, Vṛtrāsura understood Lord Viṣṇu’s purpose. Vṛtrāsura was eager to be killed by the thunderbolt manufactured according to Lord Viṣṇu’s instructions because he was sure that he would thus return home, back to Godhead. He was simply waiting for the opportunity of the thunderbolt’s being released. In effect, therefore, Vṛtrāsura told Indra, “If you want to kill me, since I am your enemy, take this opportunity. Kill me. You will gain victory, and I shall go back to Godhead. Your deed will be equally beneficial for both of us. Do it immediately.”

Vṛtrāsura not only assured King Indra that the thunderbolt was invincible, but also encouraged Indra to use it against him as soon as possible. Vṛtrāsura was eager to die with the stroke of the thunderbolt sent by Lord Viṣṇu so that he could immediately return home, back to Godhead. By hurling the thunderbolt, Indra would gain victory and enjoy the heavenly planets, remaining in the material world for repeated birth and death. Indra wanted to gain victory over Vṛtrāsura and thereby become happy, but that would not at all be happiness. The heavenly planets are just below Brahmaloka, but as stated by the Supreme Lord, Kṛṣṇa, ābrahma-bhuvanāl lokāḥ punar āvartino ’rjuna: even if one achieves Brahmaloka, he must still fall to the lower planetary systems again and again. However, if one goes back to Godhead, he never returns to this material world. By killing Vṛtrāsura, Indra would not actually gain; he would remain in the material world. Vṛtrāsura, however, would go to the spiritual world. Therefore victory was destined for Vṛtrāsura, not for Indra.

The words ahaṁ samādhāya manaḥ indicate that the most important duty at the time of death is to concentrate one’s mind. If one can fix his mind on the lotus feet of Kṛṣṇa, Viṣṇu, Saṅkarṣaṇa or any Viṣṇu mūrti, his life will be successful. To be killed while fixing his mind at the lotus feet of Saṅkarṣaṇa, Vṛtrāsura asked Indra to release his vajra, or thunderbolt. He was destined to be killed by the thunderbolt given by Lord Viṣṇu; there was no question of its being baffled. Therefore Vṛtrāsura requested Indra to release the thunderbolt immediately, and he prepared himself by fixing his mind at the lotus feet of Kṛṣṇa. A devotee is always ready to give up his material body, which is described herein as grāmya-pāśa, the rope of material attachment. The body is not at all good; it is simply a cause of bondage to the material world. Unfortunately, even though the body is destined for destruction, fools and rascals invest all their faith in the body and are never eager to return home, back to Godhead.

In Bhagavad-gītā (4.11) the Lord says:

“As devotees surrender unto Me, I reward them accordingly. Everyone follows My path in all respects, O son of Pṛthā.” Both Indra and Vṛtrāsura were certainly devotees of the Lord, although Indra took instructions from Viṣṇu to kill Vṛtrāsura. The Lord was actually more favorable to Vṛtrāsura because after being killed by Indra’s thunderbolt, Vṛtrāsura would go back to Godhead, whereas the victorious Indra would rot in this material world. Because both of them were devotees, the Lord awarded them the respective benedictions they wanted. Vṛtrāsura never wanted material possessions, for he knew very well the nature of such possessions. To accumulate material possessions, one must labor very hard, and when he gets them he creates many enemies because this material world is always full of rivalry. If one becomes rich, his friends or relatives are envious. For ekānta-bhaktas, unalloyed devotees, Kṛṣṇa therefore never provides material possessions. A devotee sometimes needs some material possessions for preaching, but the possessions of a preacher are not like those of a karmī. A karmī’s possessions are achieved as a result of karma, but those of a devotee are arranged by the Supreme Personality of Godhead just to facilitate his devotional activities. Because a devotee never uses material possessions for any purpose other than the service of the Lord, the possessions of a devotee are not to be compared to those of a karmī.

There are four objectives in human life — namely, religiosity (dharma), economic development (artha), sense gratification (kāma), and liberation (mokṣa) from the bondage of material existence. People generally aspire for religiosity, economic development and sense gratification, but a devotee has no other desire than to serve the Supreme Personality of Godhead both in this life and in the next. The special mercy for the unalloyed devotee is that the Lord saves him from hard labor to achieve the results of religion, economic development and sense gratification. Of course, if one wants such benefits, the Lord certainly awards them. Indra, for example, although a devotee, was not much interested in release from material bondage; instead, he desired sense gratification and a high standard of material happiness in the heavenly planets. Vṛtrāsura, however, being an unalloyed devotee, aspired only to serve the Supreme Personality of Godhead. Therefore the Lord arranged for him to go back to Godhead after his bodily bondage was destroyed by Indra. Vṛtrāsura requested Indra to release his thunderbolt against him as soon as possible so that both he and Indra would benefit according to their proportionate advancement in devotional service.

This verse gives the sum and substance of devotional life. One must first become a servant of the servant of the servant of the Lord (dāsānudāsa). Śrī Caitanya Mahāprabhu advised, and He also showed by His own example, that a living entity should always desire to be a servant of the servant of the servant of Kṛṣṇa, the maintainer of the gopīs (gopī-bhartuḥ pada-kamalayor dāsa-dāsānudāsaḥ). This means that one must accept a spiritual master who comes in the disciplic succession and is a servant of the servant of the Lord. Under his direction, one must then engage one’s three properties, namely his body, mind and words. The body should be engaged in physical activity under the order of the master, the mind should think of Kṛṣṇa incessantly, and one’s words should be engaged in preaching the glories of the Lord. If one is thus engaged in the loving service of the Lord, one’s life is successful.

A pure devotee never desires to gain material opportunities by rendering transcendental loving service to the Lord. A pure devotee desires only to engage in loving service to the Lord in the constant association of the Lord and His eternal associates, as stated in the previous verse (dāsānudāso bhavitāsmi). As confirmed by Narottama dāsa Ṭhākura:

To serve the Lord and the servants of His servants, in the association of devotees, is the only objective of a pure, unalloyed devotee.

A pure devotee always yearns to associate personally with the Lord and render service unto Him. The examples given in this regard are most appropriate. A small baby bird is practically never satisfied except when the mother bird comes to feed it, a small calf is not satisfied unless allowed to suck the milk from the mother’s udder, and a chaste, devoted wife whose husband is away from home is never satisfied until she has the association of her beloved husband.
