Apah, water; analah, fire; vayuh, air; kham, space; manah, mind. By 'mind' is meant its source, egoism. By buddhih, intellect, is meant the principle called mahat [Mahat means Hiranyagarbha, or Cosmic Intelligence.] which is the source of egoism. By ahankarah, egoism, is meant the Unmanifest, associated [Associated, i.e. of the nature of.] with (Cosmic) ignorance. As food mixed with position is called poison, similarly the Unmainfest, which is the primordial Cause, is called egoism since it is imbued with the impressions resulting from egoism; and egoism is the impelling force (of all). It is indeed seen in the world that egoism is the impelling cause behind all endeavour.
