There is a wide gulf between superficial dabbling in philosophy to impress people with a few stock phrases, and a sincere search for knowledge of the Absolute. Through the speculative process it is impossible to fathom the inconceivable topics concerning the Absolute Truth, for they can be understood only through the science of devotion.
His Divine Grace A. C. Bhaktivedanta Swami Prabhupada
Renunciation Through Wisdom, Chapter 5

With great love My devotees see Me and talk with Me. The happiness I feel by associating with My devotees is newer and newer at every moment. Although My desires are always fulfilled, My desire to associate with My devotees never ends.
Lord Sri Krishna
Hari-bhakti-sudhodaya 14.28

I have no attraction for performing religious rituals or holding any earthly kingdom. I do not care for sense enjoyments; let them appear and disappear in accordance with my previous deeds. My only desire is to be fixed in devotional service to the lotus feet of the Lord, even though I may continue to take birth here life after life.
Maharaja Kulashekhara
Mukunda-mala-stotra 5

Again, offering obeisances unto all you brahmanas, I pray that if I should again take my birth in the material world I will have complete attachment to the unlimited Lord Krishna, association with His devotees and friendly relations with all living beings.
Maharaja Parikshit
Srimad-Bhagavatam 1.19.16

Fools fall in love with material sense objects. As they always love sense objects, may I always love You [Lord Nrisimha]. I always meditate on You. I pray that You will never leave my heart.
Prahlada Maharaja
Vishnu Purana 1.20.19

A soul who knows the bliss that comes from the Supreme Brahman never fears.
Taittiriya Upanishad 2.7.1

O Vishnu, Your name is completely transcendental. Thus it is self-manifested. Indeed, even without properly understanding the glories of chanting Your holy name, if we vibrate Your name with at least a small understanding of its glories – that is, if we simply repeat the syllables of Your holy name – gradually we shall understand it.
Rig Veda 1.156.3

The result of chanting is that one awakens his love for Krishna and tastes transcendental bliss. Ultimately, one attains the association of Krishna and engages in His devotional service, as if immersing oneself in a great ocean of love.
