महाभूतान्यहंकारो बुद्धिरव्यक्तमेव च | इन्द्रियाणि दशैकं च पञ्च चेन्द्रियगोचराः || ६ ||
mahā-bhūtāny ahaṅkāro buddhir avyaktam eva ca indriyāṇi daśaikaṁ ca pañca cendriya-gocarāḥ
mahā-bhūtāni—the five great elements; ahaṅkāraḥ—ego; buddhiḥ—intelligence; avyaktam—the unmanifested; eva—certainly; ca—also; indriyāṇi—the senses; daśa-ekam—eleven (five knowledge senses + five action senses + mind); ca—also; pañca—five; ca—also; indriya-gocarāḥ—sense objects.
“The great elements, the ego (ahankara), the intellect (buddhi), the Unmanifest (Avyakta), the eleven senses (ten senses + mind), and the five sense objects (sound, touch, form, taste, smell) —”
Krishna here enumerates the twenty-four categories that constitute the 'kshetra' (field). These include all of manifest reality from the subtlest — the Unmanifested primordial matter (Avyakta) — down through the ego, intellect, senses, and finally the five gross elements (earth, water, fire, air, space). This is the Samkhya map of existence. The entire universe of experience, inner and outer, is encompassed in this field. The Knower stands apart from all of it.
The 24-fold field includes not just the body but the mind, ego, and even the subtlest sense of 'I am.' This is radical: even our sense of individual identity is part of the 'field' — an object of awareness, not the aware subject itself. Contemplate this: can you be aware of the feeling 'I am'? If so, you — as awareness — are already beyond it.
