Practice for Self and Others--seems a simple enough idea and very compassionate . It is of course a prerequisite for Nichiren buddhists. But what does it really mean. Separateley it's simple enough to comprehend. If you are practicing for other people then you must accept that those people are different ,or separate , from you , or your self, But doesn't Buddhism teach the oneness of all things ,beings , etc ?.So ,if you are practicing for your self doesn't that include everything else in the universe ?

The truth ,or reality , cannot be perceived through the medium of language. It must be comprehended through direct experience. Language is species specific . Instructions of how to gain enlightenment cannot be given in a spoken or written language and that's why we chant "nam myo ho renge kyo " .
