naham viriñco na kumara-naradau
na brahma-putra munayah suresah
vidama yasyehitam amsakamsaka
na tat-svarupam prthag-isa-maninah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Neither I [Lord Siva], nor Brahma, nor the Asvini-kumaras, nor Narada or the other great sages who are Brahma’s sons, nor even the demigods can understand the pastimes and personality of the Supreme Lord. Although we are part of the Supreme Lord, we consider ourselves independent, separate controllers, and thus we cannot understand His identity.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Brahma-samhita (5.33) states:
advaitam acyutam anadim ananta-rupam
adyam purana-purusam nava-yauvanam ca
vedesu durlabham adurlabham atma-bhaktau
govindam adi-purusam tam aham bhajami
“I worship the Supreme Personality of Godhead, Govinda, who is the original person. He is absolute, infallible and beginningless, and although expanded into unlimited forms, He is still the same original person, the oldest person, who always appears as a fresh youth. The eternal, blissful, all-knowing forms of the Lord cannot be understood even by the best Vedic scholars, but they are always manifest to pure, unalloyed devotees.” Lord Siva places himself as one of the nondevotees, who cannot understand the identity of the Supreme Lord. The Lord, being ananta, has an unlimited number of forms. Therefore, how is it possible for an ordinary, common man to understand Him? Lord Siva, of course, is above the ordinary human beings, yet he is unable to understand the Supreme Personality of Godhead. Lord Siva is not among the ordinary living entities, nor is he in the category of Lord Visnu. He is between Lord Visnu and the common living entity.
