"The ear is adhyāṭma, the audible aḍhibhūṭa, and ḍik (the quarters) is aḍhiḍaivaṭa. The nādis bind them. He who moves in the ear, in the audible, in the quarters, in the nādis, in prāṇa, in vijñāna, in ānanḍa, in the ākāś of the heart, and within all else—That is Āṭmā. It is that which should be worshipped. It is without old age, death, fear, sorrow, or end.
