At the very outset let me state that many theories have been propounded on this earth. Some of them survived for some time and then gradually passed out of existence; others emerged like meteors, exhibiting their dazzling radiance for a very short time, and then vanished into darkness. The mere existence of a theory is not the essential point; what is important is whether the theory promoted the welfare of all, the spiritual well-being of all -- otherwise its advent on this earth was quite useless. Such useless theories are not even worth mentioning.
Any theory will contain the seed of well-being if its firm foundation is sama-sama'ja tattva [principle of social equality]. It may survive for a very long period -- even for eternity - if it cherishes the ideal of forever promoting the welfare of all. This is the essential point.
I have already said several times, and I repeat, that while moving towards the inner world, human beings have to maintain equilibrium and equipoise in the external world. If some declare that "Brahma satyam' jaganmithya'" ["Only Supreme Consciousness is real and the world is false"], they will not be able to do anything in this "false" world. They are simply deceiving themselves - it is a sign of hypocrisy. An honest person should never resort to hypocrisy in any sphere of life; under no circumstances must he or she compromise with any unjust theory. This is the rule; this is correct. Propriety dictates this.
