Do not waste your thoughts. For it makes your mind unsteady and wavering. Take the example of a handkerchief. Is it a cloth? No, it is not. It is a bundle of threads. No, not even threads. It is just cotton. Without cotton, there can be no threads and without threads there can be no cloth. Likewise, the mind is nothing but a bundle of thoughts. Having understood this deeply, put a check on your thoughts. Even the wealth you acquire and the food you eat must be within a certain limit. Food is God, do not waste it. Help others, never hurt them. These are some key guidelines that you must follow for purposeful living.

 Fill the brain with the highest thoughts and ideals.  Place them day and night before you
and out of that will come great work. - Baba
