Chapter 12 Verse 2 as explained by Pujya Gurudev Swami Chinmayananda ji
मय्यावेश्य मनो ये मां नित्ययुक्ता उपासते ।
श्रद्धया परयोपेताः ते मे युक्ततमा मताः ॥ १२-२॥
“In this very opening stanza, Krishna points out three conditions that are absolutely necessary in order that devotion unto the Lord may yield its promised dividend. Generally, there is a feeling that the ‘Path-of-Devotion’ is very easy. It is equally true to say that no chosen ‘Path’ is difficult for the seeker who has chosen it. ‘Paths’ are different only because of the vehicles employed; in a boat we can never travel through the grand-trunk road, nor can we sail over the waves in a plane, nor on a cycle dash at 60-miles an hour! There are limitations to each vehicle. But progress is assured to the intelligent and the careful even with any such vehicle. Similarly, for self-development, each type of seeker, according to the vehicle available, chooses either the ‘Path-of-Devotion’ or the ‘Path-of- Action’ or the ‘Path-of-Knowledge.’ To each one of them, his ‘Path’ is the easiest.
