The Absolute Truth is there, just as the sun is there for everyone to see. The sun does not hide, but a person can try to hide from the sun by closing his door. One must open the door in order to see the sun. Similarly, Krishna is there, God is there, and we have to come to Krishna and take the lessons of Bhagavad-gita to learn who and what God is. – His Divine Grace A. C. Bhaktivedanta Swami Prabhupada Teachings of Lord Kapila, Chapter 13
When someone engages in Lord Krishna’s devotional service for the satisfaction of the senses and instead acquires a taste for serving Krishna, he gives up his material desires and willingly offers himself as an eternal servant of Krishna. – Sri Caitanya Mahaprabhu Sri Caitanya-caritamrta, Madhya-lila 22.41
Since the primeval Personality of Godhead is easily attained by offering Him such things as leaves, flowers, fruits, and water, which are all found without difficulty, why does one need to endeavor for liberation separately? – Narsimha Purana (Quoted in Srimad-Bhagavatam 10.14.4, Purport)
It is firmly declared that the steady adherence of transcendentalists to their respective spiritual positions constitutes real piety and that sin occurs when a transcendentalist neglects his prescribed duty. One who adopts this standard of piety and sin, sincerely desiring to give up all past association with sense gratification, is able to subdue materialistic activities, which are by nature impure. – Lord Sri Krishna Srimad-Bhagavatam 11.20.26
My dear Vaishnava, seeing a person like you is the perfection of one’s eyesight, touching your lotus feet is the perfection of the sense of touch, and glorifying your good qualities is the tongue’s real activity, for in the material world it is very difficult to find a pure devotee of the Lord. – Hari-bhakti-sudhodaya 13.2
The Lord is the eye of the eye and the ear of the ear. – Brhad-aranyaka Upanisad 4.4.18
Just as the fire of digestion, from the moment food is eaten, begins digesting it but completes the process after nine or twelve hours, so from the beginning of devotional practice, bhakti begins to destroy material life in the form of lamentation and illusion but completes the process of destruction only after some time. Thus even at the stage of practice, when lamentation and illusion have not been destroyed, one should not consider the devotee to be in samsara, the cycle of birth and death. – Srila Visvanatha Cakravarti Thakura Commentary on Srimad-Bhagavatam 3.25.33
