The difference between the Foundation Establishment Plane and the Meditation Plane lies in the genesis of the divine mind.
Once the divine mind was completed, the power of the spell was enhanced, and it was possible to comprehend heaven and earth.
Once the comprehension deepened, it could be magnified with spells or sword vapor in the form of 'will.'
In the celestial clans, there were not too many detailed records or descriptions of such things.
The only important thing was if one understood or mastered it.
There was not much written description of its nature.
But Chen Jingzhai was different in that aspect. When he cultivated, he would take time to think about it.
He would use the views and thoughts gathered from his previous lives and analyze them step by step.
This was also the reason why he comprehended the Dharma Intent so quickly.
