Śrī Caitanya Caritamrta · Text Madhya 22.160
কৃষ্ণং স্মরন্ জনঞ্চাস্য প্রেষ্ঠং নিজসমীহিতম্ ।
তত্তৎকথা-রতশ্চাসৌ কুর্যাদ্বাসং ব্রজে সদা ॥ ১৬০ ॥
kṛṣṇaṁ smaran janaṁ cāsya
preṣṭhaṁ nija-samīhitam
tat-tat-kathā-rataś cāsau
kuryād vāsaṁ vraje sadā
“ ‘The devotee should always think of Kṛṣṇa within himself and should choose a very dear devotee who is a servitor of Kṛṣṇa in Vṛndāvana. One should constantly engage in topics about that servitor and his loving relationship with Kṛṣṇa, and one should live in Vṛndāvana. If one is physically unable to go to Vṛndāvana, he should mentally live there.’
