तत्क्षेत्रं यच्च यादृक् च यद्विकारि यतश्च यत्।
स च यो यत्प्रभावश्च तत्समासेन मे श्रृणु।।13.4।।
।।13.4।।वह क्षेत्र जो है? जैसा है? जिन विकारोंवाला है और जिससे जो पैदा हुआ है तथा वह क्षेत्रज्ञ भी जो है और जिस प्रभाववाला है? वह सब संक्षेपमें मेरेसे सुन।
Now Lord Krishna is more explicitly explaining details about the tat ksetram or field of activity. Its yadrik ca or its substantial nature regarding its use and function and its purpose. Also its yad vikari or transformations and modifications along with its yatas or from whence it came meaning its origin and how it was created and for whose use. Yat refers to its attributes and qualities. Also He is inferring that knowledge about the intrinsic nature of the ksetra-jna as the knower of the ksetra which is the atma or eternal soil will be revealed as well along with its inherent potencies which is confirmed by the word prabhavas ca meaning virtues, potency and powers. Lord Krishna will give a summary of all these things.
