भूमिरापोऽनलो वायुः खं मनो बुद्धिरेव च।
अहङ्कार इतीयं मे भिन्ना प्रकृतिरष्टधा।।7.4।।
7.4 Earth, water, fire, air, ether, mind, intellect and egoism thus is My Nature divided eightfold.
7.4 Iyam, this; prakrtih, Prakrti, [Prakrti here does not mean the Pradhana of the Sankhyas.] the divine power called Maya; me, of Mine, as described; bhinna, is divided; astadha, eight-forl; iti, thus: bhumih, earth-not the gross earth but the subtle element called earth, this being understood from the statement, Prakrti (of Mine) is divided eight-fold. Similarly, the subtle elements alone are referred to even by the words water etc. 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.
