Suta Gosvami said,
The occupational activities a man performs according to his own position are only so much useless labor if they do not provoke attraction for the message of the Personality of Godhead.
Learned transcendentalists who know the Absolute Truth call this nondual substance Brahman, Paramatma or Bhagavan.
The seriously inquisitive student or sage, well equipped with knowledge and detachment, realizes that Absolute Truth by rendering devotional service in terms of what he has heard from the Vedanta-sruti.
With sword in hand, intelligent men cut through the binding knots of reactionary work [karma] by remembering the Personality of Godhead. Therefore, who will not pay attention to His message?
O twice-born sages, by serving those devotees who are completely freed from all vice, great service is done. By such service, one gains affinity for hearing the messages of Vasudeva.
Sri Krsna, the Personality of Godhead, who is the Paramatma [Supersoul] in everyones heart and the benefactor of the truthful devotee, cleanses desire for material enjoyment from the heart of the devotee who has developed the urge to hear His messages, which are in themselves virtuous when properly heard and chanted.
In the revealed scriptures, the ultimate object of knowledge is Sri Krsna, the Personality of Godhead. The purpose of performing sacrifice is to please Him. Yoga is for realizing Him. All fruitive activities are ultimately rewarded by Him only. He is supreme knowledge, and all severe austerities are performed to know Him. Religion [dharma] is rendering loving service unto Him. He is the supreme goal of life.
