To attain the technique of meditation from gross level to subtle level we can train our mind to focus on an object like your own breath, or a flower or a candle flame or a mantra or any object that you can easily focus upon. If the mind gets diverted do not feel discouraged. Gently bring the mind back to your chosen object. Persistent meditation will re-establish physical and mental equilibrium. Regular practice will induce deep sense of rejuvenation and relaxation. Pulse rate, and blood pressure and oxygen requirement comes down. Mind becomes more relaxed and receptive and can quickly pick up auto suggestions.
