Verse 13·6

महाभूतान्यहंकारो बुद्धिरव्यक्तमेव च ।इन्द्रियाणि दशैकं च पंच चेन्द्रियगोचराः ॥

mahābhūtānyahaṃkāro buddhiravyaktameva caindriyāṇi daśaikaṃ ca paṃca cendriyagocarāḥ

The Gita contents itself with a brief practical statement of the lower nature of our being in the terms of the Sankhya thinkers. First there is the indiscriminate unmanifest Energy; out of that has come the objective evolution of the five elemental states of matter; as also the subjective evolution of the senses, intelligence and ego; there are too five objects of the senses, or rather five different ways of sense cognizance of the world, powers evolved by the universal energy in order to deal with all the forms of things she has created from the five elemental states assumed by her original objective substance,—organic relations by which the ego endowed with intelligence and sense acts on the formations of the cosmos: this is the constitution of the kshetra. Then there is a general consciousness that first informs and then illumines the Energy in its works; there is a faculty of that consciousness by which the Energy holds together the relations of objects; there is too a continuity, a persistence of the subjective and objective relations of our consciousness with its objects. These are the necessary powers of the field; all these are common and universal powers at once of the mental, vital and physical Nature. Pleasure and pain, liking and disliking are the principal deformations of the Kshetra.
