PURPORT

In this verse the word atma-medhasa is commented upon by Sripada Visvanatha Cakravarti Thakura, who says that atmani means unto Lord Krsna, paramatmani. Lord Krsna is Paramatma (isvarah paramah krsnah, Brahma-samhita 5.1); therefore one whose mind is acting fully in Krsna consciousness is called atma-medhah. This may be contrasted to the word grha-medhi, which refers to one whose brain is always engrossed with thoughts of material activities. The atma-medhah is always thinking of Krsna's activities in Krsna consciousness. Since Sanat-kumara, who was a son of Lord Brahma, was fully Krsna conscious, he could point out the path of spiritual advancement. The word atma-gatih refers to that path of activities by which one can make progress in understanding Krsna.
