"Krishna's causeless Mercy is always there. If we take up that causeless Mercy a little seriously than further causeless Mercies are bestowed one after another unceasingly. Krishna is more anxious to bestow His benediction upon us than we are ready to take it. If we therefore sincerely engage ourselves in Krishna Consciousness activities, certainly we will advance more and more by the causeless Mercy of the Lord."
(Srila Prabhupada Letter, February 3, 1970)
"You have asked how Krishna is with the spirit soul in the spiritual world and the answer is that Krishna is the heart of the spirit soul, or spiritual body, So Krishna is never apart from us. Either He remains in the heart of the material body, or He remains in the heart of the spiritual body. This is Krishna's Causeless Mercy to all of His beloved children, or living entities."
(Srila Prabhupada Letter, December 12, 1968)
"It takes a little time to understand the philosophy of Krishna Consciousness but I am glad that now you are prepared to do anything for Krishna's sake, this is a great causeless mercy of Krishna upon you. Please continue your present attitude of serving Krishna and His cause, and certainly you will be successful in the matter of Krishna Consciousness even in this life."
(Srila Prabhupada Letter, November 11, 1968)
"Krishna is the Supreme Enjoyer, and we are constitutionally to be enjoyed by Him, and when we revive this constitutional position where is no more Maya. K.C. gives us the opportunity of rendering service to Krishna, and this service attitude only can replace us on our original position. Please therefore, continue to chant faithfully, and Krishna will reveal Himself, by His Causeless Mercy, and you will know everything automatically."
(Srila Prabhupada Letter, August 27, 1967)
"Yes, by Krishna's Grace all obstacles have been removed. We all prayed to Krishna that your inconveniences may be removed, and by Grace of Krishna, they have all been removed, so we feel very much thankful to the Lord. You just remain fixed up in devotional service, and all impediments that may come will be vanquished by the unlimited potency of the Lord. We should have faith in His Power, His Grace, and His Causeless Mercy."
(Srila Prabhupada Letter, March 18, 1968)
"Krishna gives assurance in the Bhagavad Gita that if one is very serious to perfect his Krishna Consciousness, then automatically, out of His Causeless Mercy, Lord Krishna gives such sincere soul the intelligence by which he can enter again into the Spiritual Sky. Actually, Krishna offers this intelligence freely to everyone, but only the fortunate persons will take to it. Unfortunate persons will speculate upon the words of Krishna and concoct some meaning according to their own sense gratification. But Krishna and His bonafide representatives are giving this knowledge freely to everyone. Now it is our duty to assimilate this knowledge and practice it. Just like the electric current is equal on all points of the electric system, but different light bulbs will take different amounts of energy. This depends upon the capacity of the bulb to accept the electric current. Similarly, the Lord is not partial to anyone, but according to one's sincere desire to render unalloyed devotional service, so will He respond to enlighten such devotee."
(Srila Prabhupada Letter, December 6, 1969)
"One should depend only on the causeless mercy of the Lord for deliverance and not even slightly on one's own strength. That is the perfect position of a Kṛṣṇa conscious person. The Lord is everyone's friend, but He is especially friendly to the surrendered soul. The simple process, therefore, is that a conditioned soul should remain surrendered to the Lord, and the Lord will give him all protection to keep him out of the clutches of material contamination."
(Śrīmad-Bhāgavatam 4.7.30, Purport)
