The wise man knows the distinction between the real Self and the mere self, but he still does sadhana so that barriers are not created for either. Sadhana is for the inner level that creates delusion or mirage; it is not Atman or the external world that create confusion but one's mental life. The internal and the external are two inseparable aspects of one single life. Practice or sadhana should be modeled in such a way that it does not lead the aspirant from one extreme to another. Some aspirants think that retiring from the world will help them attain the purpose of life. Others believe that doing actions and performing their duties in the world will fulfill the purpose of life. It is the moderate path, however, that creates a bridge between these two extremes and that is the most useful for the general public. If one is to live life happily, he needs to be aware that others are also striving to attain happiness. Consideration for others is a primary requisite for finding happiness and building a good society.
