SOUNAKA ASKED ANGIRASA:WHICH IS THAT THE KNOWLEDGE OF IT WILL MAKE EVERY OTHER THING KNOWN? ANGIRASA REPLIED: THERE ARE TWO . BRAHMAN OF LOWER STATE. & THAT OF HIGHER STATE. All the works the vedas rituals grammar that disseminates knowledge is brahman of the lower state. That which cannot be seen which has no orgin which is imperishable & that which is regarded as source of all beings & that through which the imperishable is apprehended is the higher knowledge.The upanishad stresses on achieving the higher brahman through the path of lower one but one should not get caught into the rituals & loose the highest mode .
