Shoucha and santosha come together. If there is no shoucha there can be no santosha. Constant touch or overtly in touch with other people, hugging other people all the time, if you are doing this, then you are not letting your energy to be your energy even for sometime. You are always trying to be in association with somebody. So you are lost. You do not know who you are. You do not know yourself. So keep some distance and some time for yourself. Learn to know what your real strength is, what your real weakness is, what is your true spirit.
