The causeless mercy of Lord Vishnu is unparalleled, and such mercy is perceived by the devotees only by the grace of the Lord.
Srimad Bagavatam 1.6.31,
Of sacriﬁces I am the chanting of the holy names [japa].
Bhagavat Gita 10.25
Sri Krishna is the ultimate source and shelter of all entities
Bhagavad Gita 2.10.19,
It is said, kali-kale nama-rupe krishna-avatara: Krishna descends in this Kali-yuga in the form of His holy name — Hare Krishna, Hare Rama.
Srimad Bhagavatam 9.10.53,
Krishna is the knower of everything because He does not see outside in but inside out. Gopinathji sees the Motivations, Intentions & Aspiration within our heart.
If there is little pain in the finger, I become so much disturbed because I have got intimate connection with this finger. Similarly, we have got intimate connection with Krishna and we are fallen. Therefore Krishna also feels little pain and therefore, He comes down. Krishna is feeling pain. So you become Krishna Conscious. Then Krishna will feel pleasure. — In his conversation, Vrindavan, 24th April, 1975.
