In this dhyana one does not
accept selfish pleasures,
one does not seek any reward,
and one is not moved by karmic records. 

One enters dhyana solely for the
purpose of establishing one's mind. 

And then, out of wisdom,
one returns to life in the desire realm
for the purpose of helping all
sentient beings achieve liberation. 

This dhyana is called the paramita of concentration.

- Mahaprjnaparamita Sutra
