The battery of your "car" is charged when you come to Puttaparthi, or at least when you go to some other holy place. Charge the battery of your spiritual discipline (sadhana) and then, after you return home, do not keep the car idle. If you do, the battery will run down. Take the car around and keep it going; then the battery will charge itself. So also, if you do not continue the company of the good, engagement in truth, devotional singing, and repetition of the name, then all this charging becomes a waste.
