1. Krsna feels obliged to chanters

    The maha-mantra (Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare) is also simply an address to the Lord and His energy. So to anyone who is constantly engaged in addressing the Lord and His energy, we can imagine how much the Supreme Lord is obliged. It is impossible for the Lord to ever forget such a devotee. It is clearly stated in this verse that anyone who addresses the Lord immediately attracts the attention of the Lord, who always remains obliged to him.

    From Srila Prabhupada’s “Nectar of Devotion”
