"The mind’s activities are thinking, feeling and willing, by which the mind accepts materially favorable things and rejects the unfavorable. This is the consciousness of people in general. But when one’s mind does not accept and reject but simply becomes fixed on the lotus feet of Kṛṣṇa, then one’s mind becomes as good as Vṛndāvana. Wherever Kṛṣṇa is, there also are Śrīmatī Rādhārāṇī, the gopīs, the cowherd boys and all the other inhabitants of Vṛndāvana. Thus as soon as one fixes Kṛṣṇa in his mind, his mind becomes identical with Vṛndāvana. In other words, when one’s mind is completely free from all material desires and is engaged only in the service of the Supreme Personality of Godhead, then one always lives in Vṛndāvana, and nowhere else."
(Caitanya-caritāmṛta Madhya 13.137, Purport)
