Whatever a person may be in the estimation of the social order of things, if he tries to reciprocate a feeling of love towards the Supreme Personality of Godhead and is satisfied with the blessings of the Lord, he will at once feel the highest peace of mind, for which he is hankering life after life. Peace of mind, or in other words the healthy state of mind, can be achieved only when the mind is situated in the transcendental loving service of the Lord.
His Divine Grace A. C. Bhaktivedanta Swami Prabhupada
Srimad-Bhagavatam 2.6.6, Purport
A person who gives up all fruitive activities and offers himself entirely unto Me, eagerly desiring to render service unto Me, achieves liberation from birth and death and is promoted to the status of sharing My own opulences.
Lord Sri Krishna
Srimad-Bhagavatam 11.29.34
Whatever combined sweetness can be found in all the sounds of the universe disappears into the sweetness of the smallest hint of a vibration from Krishna’s flute.
Srila Rupa Goswami
Sri Laghu-bhagavatamrita 1.5.532
Every one of the millions and millions of cowherds – the children, young people, and elders – thinks, “I alone am most dear to Krishna.” Just as the pure way they behave toward Krishna always confirms this ecstatic mentality, so does the way He behaves toward every one of them. Yet none of them ever become satiated. Their love shows a thirst that is the mother of sheer humility and that simply grows stronger and stronger.
Sri Sarupa
Sri Brihad-bhagatamrita 3.6.211–213
All the names of Vishnu give liberation (mukti), while Krishna’s names give love of God (prema).
Padma Purana
Patala-khanda, Mathura-mahatmya)
The name Durga, by which I am known, is Her name. The qualities for which I am famous are Her qualities. The majesty with which I am resplendent is Her majesty. That Maha-Lakshmi, Sri Radha, is nondifferent from Sri Krishna. She is His dearmost sweetheart and the crest-jewel of His beloveds.
Sri Durga Devi
Sammohana-tantra, Quoted by Jiva Goswami in his commentary on Brahma-samhita 5.3–4
Only a person who can count all the particles of dust in the world may fully enunciate the heroic deeds of Lord Vishnu.
Rig Veda 1.154.1
Effort in remembering Krishna is not necessary for the devotee who hears and chants about Him. Even without great effort by the devotee, the Lord spontaneously enters the devotee’s heart.
Srila Vishvanatha Chakravarti Thakura
Commentary on Srimad-Bhagavatam 2.8.4
