श्रीभगवानुवाच:इदं शरीरं कौन्तेय क्षेत्रमित्यभिधीयते ।एतद्यो वेत्ति तं प्राहुः क्षेत्रज्ञ इति तद्विदः ॥
śrībhagavānuvāca:idaṃ śarīraṃ kaunteya kṣetramityabhidhīyateetadyo vetti taṃ prāhuḥ kṣetrajña iti tadvidaḥ
The Blessed Lord said: This body, O son of Kunti, is called the Field; that which takes cognizance of the Field is called the Knower of the Field by the sages.
Gītā 13·2First, the whole of existence must be regarded as a field of the soul’s construction and action in the midst of Nature. The Gita explains the kṣetram, field, by saying that it is this body which is called the field of the spirit, and in this body there is someone who takes cognizance of the field, kṣetrajña, the knower of Nature. It is evident, however, from the definitions that succeed that it is not the physical body alone which is the field, but all too that the body supports, the working of nature, the mentality, the natural action of the objectivity and subjectivity of our being.
