Bhagavad Gita · 13.4

तत्क्षेत्रं यच्च यादृक्च यद्विकारि यतश्च यत्।स च यो यत्प्रभावश्च तत्समासेन मे शृणु॥

tat kṣhetraṁ yach cha yādṛk cha yad-vikāri yataśh cha yat sa cha yo yat-prabhāvaśh cha tat samāsena me śhṛṇu

Hear from me briefly what that field is, what its nature is, what its modifications are, where it comes from, who the knower is, and what his powers are.
