Christos is the Greek version of the word Krsna. The main point is to follow the injunctions of the Vedic scriptures that recommend chanting the name of God in this age. I have not come to teach you, but only to request you to please chant the name of God. The Bible also demands this of you. The mind is always concocting objects for happiness.
Happiness is here.
Happiness is there. In this way the mind is taking us anywhere and everywhere. It is as though we are riding on a chariot behind an unbridled horse. We have no power over where we are going but can only sit in horror and watch helplessly. Hare Rama, Hare Rama, Rama Rama, Hare Hare-then the wild horses of the mind will gradually come under our control.
