BG Chap 8 - The favorable situation of devotional service
A person who accepts the path of devotional service and thus knows the glories of Kṛṣṇa, is not bereft of the results derived from studying the Vedas, performance of sacrifice and austerity, and giving in charity. He attains the Lord’s eternal abode. Results such as Svarga or a kingdom are promised from thoroughly studying the Vedas and following rules such as observing celibacy and serving the guru, from precisely performing sacrifice complete with all parts, from correctly undergoing austerities according to the rules of scripture, and from giving charity in the proper manner with faith while examining the suitability of place, time and person. But all of these promised results are surpassed by the devotee. Knowing the glories of the Lord and by mercy of devotee association, the devotee considers all these activities as insignificant as grass, devoid of the happiness they promise.
