"The genitals is aḍhyāṭma, the secretion is aḍhibhūṭa, and Prajāpaṭi is aḍhiḍaivaṭa. The nādis bind them. He who moves in the genitals, secretion, Prajāpaṭi, the nādis, prāṇa, vijñāna, ānanḍa, 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.
