You are not bound. You have got free will. You cannot change the experiences, the results of Prarabdha but you can change your future by right thinking and right action and thus make your will pure and irresistible. You can attain Self-realisation with the help of a dynamic will.
Change the mind, and you can change the body.
Common sense is the fundamental factor in all spiritual disciplines. No rule is an eternal rule. Rules change from place to place, time to time and from one condition to another condition.
