Bhagavad - Gītā – 18:65
pratijāne priyo 'si me
mat-manāḥ - thinking of Me; bhava - just become; mat-bhaktaḥ - My devotee; mat-yājī - My worshiper; mām - unto Me; namaskuru - offer your obeisances; mām - unto Me; eva - certainly; eṣyasi - you will come; satyam - truly; te - to you; pratijāne - I promise; priyaḥ - dear; asi - you are; me - to Me.
Always think of Me, become My devotee, worship Me and offer your homage unto Me. Thus you will come to Me without fail. I promise you this because you are My very dear friend.
The most confidential part of knowledge is that one should become a pure devotee of
Krishna and always think of Him and act for Him.
One should not become an official meditator. Life should be so molded that one will always have the chance to think of Kṛishṇa.
One should always act in such a way that all his daily activities are in connection with Kṛishṇa.
He should arrange his life in such a way that throughout the twenty-four hours he cannot but think of Kṛishṇa.
And the Lord's promise is that anyone who is in such pure Kṛiṣhṇa consciousness will certainly return to the abode of Kṛishṇa, where he will be engaged in the association of Kṛishṇa face to face.
This most confidential part of knowledge is spoken to Arjuna because he is the dear friend of Kṛiṣhṇa. Everyone who follows the path of Arjuna can become a dear friend to Kṛiṣhṇa and obtain the same perfection as Arjuna.
These words stress that one should concentrate his mind upon Kṛiṣhṇa — the very form with two hands carrying a flute, the bluish boy with a beautiful face and peacock feathers in His hair.
There are descriptions of Kṛiṣhṇa found in the Brahma-saḿhitā and other literatures. One should fix his mind on this original form of Godhead, Kṛiṣhṇa.
One should not even divert his attention to other forms of the Lord. The Lord has multi-forms as Viṣṇu, Nārāyaṇa, Rāma, Varāha, etc., but a devotee should concentrate his mind on the form that was present before Arjuna.
