इत्यस्या हृदयं लोके नान्यो मद् वेद कश्चन ॥ ४२ ॥
kim anūdya vikalpayet
ity asyā hṛdayaṁ loke
nānyo mad veda kaścana
kim — what; vidhatte — enjoins (in the ritualistic karma-kāṇḍa); kim — what; ācaṣṭe — indicates (as the object of worship in the devatā-kāṇḍa); kim — what; anūdya — describing in different aspects; vikalpayet — raises the possibility of alternatives (in the jñāna-kāṇḍa); iti — thus; asyāḥ — of Vedic literature; hṛdayam — the heart, or confidential purpose; loke — in this world; na — does not; anyaḥ — other; mat — than Me; veda — know; kaścana — anyone.
In the entire world no one but Me actually understands the confidential purpose of Vedic knowledge. Thus people do not know what the Vedas are actually prescribing in the ritualistic injunctions of karma-kāṇḍa, or what object is actually being indicated in the formulas of worship found in the upāsanā-kāṇḍa, or that which is elaborately discussed through various hypotheses in the jñāna-kāṇḍa section of the Vedas.
The Supreme Personality of Godhead is the Absolute Truth, Lord Śrī Kṛṣṇa. Since the Lord is the source, maintainer and ultimate goal of Vedic knowledge, He is veda-vit, or the only true knower of Vedic knowledge. So-called philosophers, either Vedic scholars or ordinary men, may give their sectarian opinion, but it is the Lord Himself who knows the confidential purpose of the Vedas. The Lord is the only actual shelter and lovable object for all living entities. As He states in the Tenth Chapter of Bhagavad-gītā (10.41):
śrīmad ūrjitam eva vā
tad tad evāvagaccha tvaṁ
“Know that all beautiful, glorious and mighty creations spring from but a spark of My splendor.” All beautiful, extraordinary and powerful manifestations are insignificant displays of the Lord’s own opulences. Although ordinary people may quarrel over the purpose of religion, the actual purpose is one, Kṛṣṇa consciousness, or pure love of Godhead. All Vedic formulas are understood to be preliminary stages leading to the perfect stage of Kṛṣṇa consciousness, in which one fully surrenders to the devotional service of the Lord. The pure devotees of the Lord represent Him within this world and never speak anything which is not authorized by the Lord. Because they are repeating the Lord’s own words, they are also to be understood as true knowers of the Veda.
