simple spiritual exercises to practise

Question: I am 28 year old physician in States. I lead a fairly busy life. Please give me some simple spiritual exercises to practise. Looking forward to hearing from you.

Answer: Thank you for your letter & interest in spiritual practice. You should determine to spend fifteen minutes everyday in the morning before your work. Just sit and try to pray to whichever God you believe in for one or two minutes; and then try to concentrate your mind on ‘Om’ or on any light or on space. If you sincerely put your effort, you will be able to concentrate on it. It should bring peace. Continue it for one or two months and get back to me.
