Since time immemorial each living entity has accumulated the various reactions of his good and bad work. As such, he is continuously ignorant of his real constitutional position. One’s ignorance can be removed by the instruction of the Bhagavad-gita, which teaches one to surrender unto Lord Sri Krishna in all respects and become liberated from the chained victimization of action and reaction, birth after birth.

Bhagavad-gita As It Is 2.50, Purport
Mantra diksha means the receipt of transcendental knowledge. Transcendental knowledge smashes down to their foundation all our seemingly beautiful philosophical mansions, built on empiricism, and erects in their place an actual foundation of eternal transcendental knowledge, cleansing the ground of all contaminations.
Srila Bhaktisiddhanta Sarasvati Thakura
Uncommon Conversations, Conversation 7
My devotees may or may not know exactly what I am, who I am, and how I exist, but if they worship Me with unalloyed love, then I consider them to be the best of devotees.
Lord Sri Krishna
Srimad-Bhagavatam 11.11.33
All living beings find that the Supreme Person is sweet like nectar.
Brihad-aranyaka Upanishad 2.5.14
The peaceful hearts of My devotees are the homes the goddess of fortune and I like best. I reside in those homes, and I call them Vaikuntha.
Lord Vishnu
Hari-bhakti-sudhodaya 14.57
Those who meditate on the Supreme Personality of Godhead bring destruction to their continued residence in the material world. Those who meditate on the material world bring destruction to themselves.
Narada Purana
Quoted in Paramatma-sandarbha 58.29
When scriptures describe the Lord of the universe as devoid of qualities, they mean He has no material qualities like those belonging to inferior objects.
Padma Purana, Uttara-khanda 255.39-40
O Narada, O great sage, the great thinkers can know Him [the Personality of Godhead] when completely freed from all material hankerings and when sheltered under undisturbed conditions of the senses. Otherwise, by untenable arguments, all is distorted, and the Lord disappears from our sight.
Lord Brahma
Srimad-Bhagavatam 2.6.41
In Vaikuntha each devotee sees the Supreme Lord Sri Narayana manifest as the particular Lord he worships, with a form of suitable complexion and other qualities.
Sri Narada Muni
Brihad-bhagavatamrita 2.4.147
Devotional sentiments are evoked by the purifying association of advanced devotees. The jiva is able to come into close contact with a shuddha-bhakta, a pure devotee, only by accruing sufficient sukriti, pious credits, for many previous births.
Brihan-naradiya Purana 4.33
