A common question by a person with Self-Knowledge: “Having done Śravaṇa and Manana, I am very clear I am Brahman. But in my behavior I do not find myself, ‘I am Brahman'. Why?“
You may have to deal with another problem – that of “viparīta-bhāvanā“.
It's caused by your memories.
There is another parallel reality – the Emotional reality.
This emotional reality is the reality of the child.
In everybody there is a child. And the child is in form of the Unconscious (saṃskāra/vāsanā).
The Unconscious does not know (nor care), that person can genuinely claim with absolute understanding and clarity, “aham brahmāsmi“.
Meaning, even though the person has come to discover, “I am Brahman” – sometimes his/her Unconscious can interfere in the appreciation of this Self-Knowledge.
It will not let you enjoy the fruits of this “aham brahmāsmi” understanding entirely. Because Unconscious is still waiting for attention.
This phenomena is called: “viparīta-bhāvanā“.
The solution thus is:
A persistent sādhana of Nididhyāsana. Meaning you continue contemplating upon what you have understood.
Yes, self-inquiry likely continues until last breath. Except now it's not for sake of “Who am I?“, but for sake of resolving Obstacles which deny one from enjoyment of knowledge of Limitlessness/Freedom.
Because some Unconscious saṃskāras are deeply ingrained, mainly due to Childhood issues.
For example, by age 5-6, dominant life views have already been deeply etched in child's Brain. And this can interfere with qualities like Compassion, humor, friendliness and overall cheerfulness.
Nididhyāsana isn't necessary though for a wise person. Because they know all problems (including the Unconscious) belongs to Mityhā.
But ironically wise person has nothing to either lose nor gain by attending to the present saṃskāras/vāsanās. So in most cases he/she gladly continues the journey of growth and purification.
Only difference is, the growth/purification is expressed out of Love. And not of fear/desire or sense of lack.
So nothing really changes.
This is why Self-realized Vedāntin's continue listening to Vedānta sessions and reading Śruti (scriptures). Because it's a sādhana of Nididhyāsana.
