Allowing Openness

Intellectual openness is not knowing (yet still seeking).
Emotional openness is not minding, not caring (without giving up).
Physical openness is freedom and space in the joints.
In any case, openness cannot be manufactured; it is manifest in reality through the practice of allowing.

Then the proof of the pudding is in the way a person accepts and uses himself. In the case of a buddha, evidently, it is with good cheer and a certain economy of effort.
