Identification with the body keeps one's mind within the boundaries of the body. Therefore, one divides space into the space of one's own body and the space in which other bodies exist.

 
Let’s imagine that our body suddenly dissolves but we remain conscious. What will then exist in its place? 

In the process of modelling, the mind moves freely in the space that contains all bodies, the boundaries of which are only visual.

 
The mind of a sculptor is resting in the space of the model's body and works with it in a third place.

 
At the time of the modelling, a variety of spatial bodily forms gather around this place.

 
These forms gradually move closer to each other until they fit together and condense into a portrait of the model.

 

*Resting mind: The mind abides in one place with full awareness (refers to the Shamatha (Shiné) meditation practice in the schools of Tibetan Mahayjana Buddhism).
