Meaningfulness and meaninglessness...

Free the mind from egoism, identification and attachment, then all the actions (including yoga practice) that had been performed, is being performed and will be performed through this body and mind will be free from 'meaningfulness' and 'meaninglessness'.

There is no 'I'.
There is no 'I am'.
There is no 'I am a yogi'.
There is no 'I am a good yogi'.
There is no 'I am practicing yoga'.
There is no 'I am receiving the fruit of practicing yoga'.

It's just actions and the consequences of actions.
It's neither 'meaningful' nor 'meaningless'.

Impermanent changes are happening unceasingly in all the names and forms, but there is no 'I' existing in all these names and forms, nor do 'I' exist in all the impermanent changes.

Be happy.
