11.21.42

किं विधत्ते किमाचष्टे किमनूद्य विकल्पयेत् । इत्यस्या हृदयं लोके नान्यो मद् वेद कश्चन ॥ ४२ ॥

kim

anūdya
describing in different aspects
vikalpayet
raises the possibility of alternatives (in the jñāna-kāṇḍa)
iti

anyaḥ
other
mat

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.
