As stated in several places, bhaktyÄ mÄm abhijÄnÄti: only by devotional service can the Supreme Lord be understood. The intelligent person, the devotee, does not bother much about the practices mentioned in text 46 (mauna-vrata-Å›ruta-tapo-’dhyayana-sva-dharma). After understanding the Supreme Lord through devotional service, such devotees are no longer interested in studies of the Vedas. Indeed, this is confirmed in the Vedas also. The Vedas say, kim arthÄ vayam adhyeá¹£yÄmahe kim arthÄ vayam vaká¹£yÄmahe. What is the use of studying so many Vedic literatures? What is the use of explaining them in different ways? Vayam vaká¹£yÄmahe. No one needs to study any more Vedic literatures, nor does anyone need to describe them by philosophical speculation. Bhagavad-gÄ«tÄ (2.52) also says:
yadÄ te moha-kalilaá¹
buddhir vyatitariá¹£yati
tadÄ gantÄsi nirvedaá¹
śrotavyasya śrutasya ca
When one understands the Supreme Personality of Godhead by executing devotional service, one ceases the practice of studying the Vedic literature. Elsewhere it is said, ÄrÄdhito yadi haris tapasÄ tataḥ kim. If one can understand the Supreme Personality of Godhead and engage in His service, there is no more need of severe austerities, penances and so on. However, if after performing severe austerities and penances one does not understand the Supreme Personality of Godhead, such practices are useless.
