Verse
महाभूतान्यहंकारो बुद्धिरव्यक्तमेव च ।इन्द्रियाणि दशैकं च पंच चेन्द्रियगोचराः ॥
The indiscriminate unmanifest Energy; the five elemental states of matter; the ten senses and the one (mind), intelligence and ego; the five objects of the senses. (This is the constitution of the Kshetra.) Liking and disliking, pleasure and pain (these are the principal deformations of the Kshetra); consciousness, collocation, persistence; these, briefly described, constitute the Field and its deformations.
