Fruitive activities and speculative knowledge cannot independently liberate anyone, but devotional service, independent of karma and jñāna, is so potent that one who has fixed his mind at the lotus feet of Kṛṣṇa is guaranteed not to meet the Yamadūtas, the order carriers of Yamarāja, even in dreams.
(Srimad Bhagavatam---6:1---summary).

Realized devotees are like bumblebees maddened by their own mellows at Kṛṣṇa's lotus feet. The scent of those lotus feet perfumes the entire world. Who is the realized soul that could give them up?
(Sri Caitanya Caritamrta----3:20:156---translation).

The Lord says, "I give him intelligence." What is that intelligence? Yena mām upayānti te. The Lord gives one the intelligence to cross over the ocean of nescience and come back home, back to Godhead. In conclusion, the cause of all causes, the Absolute Truth, or Supreme Brahman, cannot be understood by philosophical speculation, but He reveals Himself to His devotee because the devotee fully surrenders unto His lotus feet.
(Srimad Bhagavatam---4:11:23---purport).

The mind is the director of the senses, and Lord Aniruddha is the director of the mind. In order to execute devotional service, one has to fix his mind on the lotus feet of Kṛṣṇa; therefore Lord Śiva prays to the controller of the mind, Lord Aniruddha, to be pleased to help him engage his mind on the lotus feet of the Lord.
(Srimad Bhagavatam--4:26:36---purport).

The chance to enjoy matter is given to the conditioned souls in the material world, and side by side they are given the chance to understand their real constitutional position. Those fortunate living entities who catch the truth and surrender unto the lotus feet of Vāsudeva after many, many births in the material world join the eternally liberated souls and thus are allowed to enter into the kingdom of Godhead. After this, such fortunate living entities need not come again within the occasional material creation.
(Srimad Bhagavatam---1:3:1---purport).
