Commentary by TKV Desikachar:

Commentary by S Ramaswami:

“There are Yogi who have particular minds.
Possibly to work out Karma by creating several Citta.
What is needed as an impulse? Only Asmitā alone is required.
A person who has practised Saṃyama can create Citta and experience them.
However he has still not got over Asmitā.
This is driving him to do this.
The concept of Siddhi should be considered again here.
The path of the Yogi towards Siddhi is like that of a person going through a market place. We may look at the stalls, examine their wares but not buy or use. To do this is an action of Asmitā.
Nirmāṇa Citta can be used for good if a person wants to teach.
i.e Bodhisattva in Buddhism
These created minds can be terminated at will, that is why they do not collect latencies of nescience and thus do not give rise to bondage.
How does this Asmitā enter or create another mind?Anything mentioned here should not violate the theory of Karma.
So different minds can be created to work off Karma and thus avoid future births for the individual.”
