Taking to Krṣṇa Consciousness

man-manā bhava mad-bhakto mad-yājī mām namaskuru mām evaiṣyasi yuktvaivam ātmānam matparāyaṇaḥ
“Always think of Me. Become My devotee. Worship Me, and offer your homage unto Me. The result is that you will come to Me without fail. I promise you this, because you are My very dear friend. Engage your mind always in thinking of Me, engage your body in My service; and surrender unto Me. Completely absorbed in Me, surely will you come to Me.” (Bg. 18.65, 9.34)
The phrase  man-manā bhava mad-bhakto  means “just be always conscious of Me.” This then is Krṣṇa consciousness. In  Bhagavad-gītā  Krṣṇa is repeatedly saying that we should worship Him, offer obeisances unto Him and then come to Him.  Bhagavad-gītā  clearly points to the absolute necessity of Krṣṇa consciousness, and  Bhagavad-gītā  is accepted as the essence of the  Upaniṣads . Even from the historical point of view, it has no comparison. It has been calculated on the basis of archeological evidence that Krṣṇa spoke  Bhagavad-gītā  on the Battlefield of Kurukṣetra more than five thousand years ago. So this Krṣṇa consciousness movement, even from the historical point of view, is five thousand years old. Its philosophy is the oldest in the history of the world. If we wish to trace it even further back, we find that Śrī Krṣṇa spoke it earlier to the sun-god. Krṣṇa is eternal, and consciousness of Krṣṇa is also eternal. In
