Vedic Thoughts
There are many instances in the transcendental histories of the world of an impersonalist who has later become a devotee. But a devotee has never become an impersonalist. This very fact proves that on the transcendental steps, the step occupied by a devotee is higher than the step occupied by an impersonalist.
His Divine Grace A.C. Bhaktivedanta Swami Prabhupāda Śrīmad-Bhāgavatam 1.18.16, Purport
Those who are afraid of material existence worship Vedic literature. Some worship smṛti, the corollaries to Vedic literature, and others worship the Mahābhārata. As far as I am concerned, I worship Mahārāja Nanda, the father of Kṛṣṅa, in whose courtyard the Supreme Personality of Godhead, the Absolute Truth, is playing.
Raghupati Upādhyāya Padyāvalī 126
For a person devoid of devotional service, birth in a great family or nation, knowledge of revealed scripture, performance of austerities and penance, and chanting of Vedic mantras are like the ornaments on a dead body. Such ornaments simply serve the concocted pleasures of the general populace.
Hari-bhakti-sudhodaya 3.12
If one is unhappy to see the distress of other living beings and happy to see their happiness, his religious principles are appreciated as imperishable by exalted persons who are considered pious and benevolent.
Śrī Dadhīci Muni Śrīmad-Bhāgavatam 6.10.9
Those who seriously follow the methods of achieving Me that I have personally taught attain freedom from illusion, and upon reaching My personal abode at last perfectly understand the Absolute Truth.
Lord Śrī Kṛṣṅa Śrīmad-Bhāgavatam 11.20.37
Even though liberation destroys the bondage of material existence, I have no desire for liberation in which I would forget that You are the master and I am your servant.
Śrī Hanumān to Lord Rāmacandra Cited in Bhakti-rasāmṛta-sindhu 1.2.49
Pure love for Kṛṣṅa is eternally established in the hearts of living entities. It is not something to be gained from another source. When the heart is purified by hearing and chanting [about Kṛṣṅa], the living entity naturally awakens.
Lord Śrī Caitanya Mahāprabhu Śrī Caitanya-caritāmṛta, Madhya 22.107
