There are two types of pain in life. A pain that occurs while walking on the path of discipline. Another pain arises from the regret that comes from not doing the work of necessity and choice. The pain of discipline bothers us for some time, the pain of regret is there all the time. Trying to do the work we want to do, neither exhausts us nor hurts us.
There is something in our mind and we are speaking something. Our talk to others is not completely true. Leave aside the big things, even in small matters we cannot keep our truth. Our own feelings, wants and needs are buried in our mind. We tell many such lies which are not needed.
