The Supreme Personality of Godhead cannot be forgotten even for a moment by His surrendered devotees. The devotee understands that the Lords causeless mercy is beyond his estimation; he cannot know how much he is benefited by the grace of the Lord. The more a devotee engages himself in the devotional service of the Lord, the more encouragement is supplied by the energy of the Lord. In the Bhagavad-gita the Lord says that to those who are constantly engaged in devotional service with love and affection, the Supreme Personality of Godhead gives intelligence from within, and thus they may make further progress. Being so encouraged, the devotee can never forget, at any moment, the Personality of Godhead. He always feels obliged to Him for having achieved increased power in devotional service by His grace. Saintly persons like Sanaka, Sanatana and Lord Brahma were able to see the entire universe, by the mercy of the Lord, through knowledge of the Lord. The example is given that a person may apparently abstain from sleep all day, but as long as he is not spiritually enlightened he is actually sleeping. He may sleep at night and perform his duties in the daytime, but as long as he does not come to the platform of working in spiritual enlightenment he is considered to be always sleeping. A devotee, therefore, never forgets the benefit derived from the Lord.
