Avasāna (Destination, Resting-Place)
Śaṅkara often uses it to mean the truth into which the illusory appearance is finally resolved.
VIII.3, is a reply to questions by Arjuna, one of which is ‘what is adhy-ātma?’ The term has been used in III.30, where Arjuna is told to perform actions ‘with mind on the self’ (adhyātma-cetasā). At that time he does not know of the Self-as-Brahman, and Śaṅkara there interprets it as the individual self, to be thought of as a servant. Here the Lord explains the term adhyātma as sva-bhāva, individual selfhood, to be further mentioned in XVII.2. But Śaṅkara adds:
That self which, overseeing a body, sets out as its inner self, and truly comes to rest (avasāna) as the highest Brahman, is the svabhāva selfhood which is to be called adhy-ātman Selfhood. (Ātmānam deham adhirkṛtya pratyag-ātmatayā pravṛttam paramārtha-Brahmāvasānam vastu svabhāva adhyātmam ucyate).
In IX.10 he says:
‘I am in pain’, ‘I will do this’, ‘I will know that’ – is all based on knowledge (avagati-niṣṭhā), (and) comes down to knowledge (avagaty-avasāna).
