Brihadaranyaka Upanishad 1.49

स वा एष पुरुषोऽन्नरसमयः — तस्येदमेव शिरः — अयं दक्षिणः पक्षः — अयमुत्तरः पक्षः — अयमात्मा — इदमधिष्ठानम् ॥

sa va esha purusho'nnarasamayah — tasyedam eva shirah — ayam dakshinah pakshah — ayam uttarah pakshah — ayam atma — idam adhishthanam ||

This person is made of the essence of food. This is his head; this is his right side; this is his left side; this is his body; this is his lower part, his support.

वह यह पुरुष अन्नरसमय है। उसका यह शिर है, यह दक्षिण पंख है, यह उत्तर पंख है, यह आत्मा है, यह अधिष्ठान (आधार) है।
