Samskaras are formed by thought and by action. Action is unavoidable. Lord Krishna says in the Gita, “Even I cannot be idle for a moment, because if I am idle or stop actions, the universe will collapse.” So action is unavoidable. Once we are born on this world, we have to act – even breathing is an activity. Now, how to avoid samskaras when the action is inevitable, unavoidable? By acting in such a way that what I do and what I think don’t make impressions upon me.
