न जायते म्रियते वा कदाचि
न्नायं भूत्वा भविता वा न भूयः।
अजो नित्यः शाश्वतोऽयं पुराणो
न हन्यते हन्यमाने शरीरे।।2.20।।
2.20 Never is this One born, and never does It die; nor is it that having come to exist, It will again cease to be. This One is birthless, eternal, undecaying, ancient; It is not killed when the body is killed.
2.20 As the self is eternal for the reasons mentioned (above), and hence free from modifications, it is said that all the attributes of the insentient (body) like birth, death etc., never touch the self. In this connection, as the statement, It is never born, It never dies is in the present tense, it should be understood that the birth and death which are experienced by all in all bodies, do not touch the self. The statement Having come into being once, It never ceases to be means that this self, having emerged at the beginning of a Kalpa (one aeon of manifestation) will not cease to be at the end of the Kalpa (i.e., will emerge again at the beginning of the next Kalpa unless It is liberated). This is the meaning - that birth at the beginning of a Kalpa in bodies such as those of Brahman and others, and death at the end of a Kalpa as stated in the scriptures, do not touch the self. Hence, the selves in all bodies, are unborn, and therefore eternal. It is abiding, not connected, like matter, with invisible modifications taking place. It is primeval; the meaning is that It existed from time immemorial; It is even new i.e., It is capable of being experienced always as fresh. Therefore, when the body is slain the self is not slain.
