"That which joins one place (or centre) with another is the nādis which bind them. The eye is aḍhyāṭmā, (pertaining to the body); the visible objects are āḍhibhūṭa (pertaining to the elements) and the sun is aḍhidaivaṭa (spiritual). The nādis form their bond (or connect them). He who moves in the eye, in the visible, in the sun, in the midis, 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.
