Space

AH Almaas describes Space in the following way:

Space brings about expansion in the qualities of our senses, our sensations, and our mental capacities. 
It deepens our intuition. It expands our awareness into new dimensions of ourselves, some we would never have conceived could exist. 
It brings new capacities for perception and experience. 
In addition, space has the surprising and powerful capacity of expanding itself, continuously increasing the openness and dissolution of boundaries, allowing ever-greater understanding of ourselves and our minds.

In the Diamond Logos Academy it is traditionally taught first as it helps students take enough space from their issues to see them more clearly.
