These are Vedic instructions. One must have full faith in the words of the spiritual master and similar faith in the Supreme Personality of Godhead. Then the real knowledge of atma and Paramatma and the distinction between matter and spirit will be automatically revealed. This atma-tattva, or spiritual knowledge, will be revealed within the core of a devotees heart because of his having taken shelter of the lotus feet of a mahajana such as Prahlada Maharaja.6.23]. One should have complete faith in the guru, who helps the disciple make progress in spiritual life. As soon as the disciple thinks independently, not caring for the instructions of the spiritual master, he is a failure (yasyaprasadan na gatih kuto pi). Aditi very strictly followed the instructions of her husband and spiritual master, and thus she was successful.
