मतं च वासुदेवस्य सञ्जहारार्जुनो द्वयम् ॥ ३२ ॥
loka-vyatikaraṁ ca tam
mataṁ ca vāsudevasya
Thus seeing the disturbance of the general populace and the imminent destruction of the planets, Arjuna at once retracted both brahmāstra weapons, as Lord Śrī Kṛṣṇa desired.
The theory that the modern atomic bomb explosions can annihilate the world is a childish imagination. First of all, the atomic energy is not powerful enough to destroy the world. And secondly, ultimately it all rests on the supreme will of the Supreme Lord because without His will or sanction nothing can be built up or destroyed. It is foolish also to think that natural laws are ultimately powerful. Material nature’s law works under the direction of the Lord, as confirmed in the Bhagavad-gītā. The Lord says there that natural laws work under His supervision. The world can be destroyed only by the will of the Lord and not by the whims of tiny politicians. Lord Śrī Kṛṣṇa desired that the weapons released by both Drauṇi and Arjuna be withdrawn, and it was carried out by Arjuna at once. Similarly, there are many agents of the all-powerful Lord, and by His will only can one execute what He desires.
