The Most Confidential Knowledge

man-manā bhava mad-bhakto
mad-yājī māṁ namaskuru
mām evaiṣyasi yuktvaivam
ātmānaṁ mat-parāyaṇaḥ
TRANSLATION
Engage your mind always in thinking of Me, offer obeisances, and worship Me. Being completely absorbed in Me, surely you will come to Me.
(BG 9.34)

bala kṛṣṇa, bhaja kṛṣṇa, gāo kṛṣṇa-nāma
kṛṣṇa vinu keha kichu nā bhāviha āna
yadi āmā’-prati sneha thāke sabākāra
tabe kṛṣṇa-vyatirikta nā gāibe āra
ki śayane, ki bhojane, kibā jāgaraṇe
aharniśa cinta kṛṣṇa, balaha vadane
TRANSLATION
Glorify Kṛṣṇa, worship Kṛṣṇa, and chant the name of Kṛṣṇa. Do not think of anything other than Kṛṣṇa.
If you have any affection for Me, then don’t speak about any topics other than Kṛṣṇa.
Whether you are sleeping, eating, or waking, day and night think of Kṛṣṇa and chant His name.
(Sri Caitanya Bhagavata Madhya-khaṇḍa 28.026- 28.028)
