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.

In this verse the word bhuyat may be understood to mean let there be. Prahlada Maharaja offers his blessings to his class friends, saying, Also become faithful like me. Become bona fide Vaisnavas. A devotee of the Lord desires for everyone to take to Krsna consciousness. Unfortunately, however, people sometimes do not have staunch faith in the words of the spiritual master who comes by the disciplic succession, and therefore they are unable to understand transcendental knowledge. The spiritual master must be in the line of authorized disciplic succession, like Prahlada Maharaja, who received the knowledge from Narada. If the class friends of Prahlada Maharaja, the sons of demons, were to accept the truth through Prahlada, they would certainly also become fully aware of transcendental knowledge.

The words vaisaradi dhih refer to intelligence concerning the Supreme Personality of Godhead, who is extremely expert. The Lord has created wonderful universes by His expert knowledge. Unless one is extremely expert, he cannot understand the expert management of the supreme expert. One can understand, however, if one is fortunate enough to meet a bona fide spiritual master coming in the disciplic succession from Lord Brahma, Lord Siva, Mother Laksmi or the Kumaras. These four sampradayas, or disciplic successions of knowledge and transcendence, are called the Brahma-sampradaya, Rudra-sampradaya, Sri-sampradaya, and Kumara-sampradaya. Sampradaya-vihina ye mantras te nisphala matah. The knowledge of the Supreme received from such a sampradaya, or disciplic succession, can give one enlightenment. If one does not take to the path of disciplic succession, it is not possible for one to understand the Supreme Personality of Godhead. If one understands the Supreme Lord through devotional service with faith in the disciplic succession and then advances further, he awakens his natural love for God, and then his success in life is assured.
