We must form a habit of being continuously in communion with God and basically becoming a good person, thinking good thoughts at all times - remember as you think so you become. There are said to be three paths, that of knowledge, devotion, and action. Action has to be performed by every being, but to reach supreme bliss, the action and its result must be surrendered to The Lord. Such an attitude leads to true renunciation. Mere giving up of action does not constitute renunciation.
Devotion is what keeps one on the path to surrender.
The mind is undoubtedly very unsteady and controlled through intense practice. Knowledge is the outcome of our search. This science takes us on the path of devotion by our actions to the supreme goal of life.
