If you have any desire to surpass others, or any thought of your own ability, this is egoism and possessiveness.

These are sicknesses in the context of nirvana, so The Nirvana Sutra says,

“Space can contain everything, but space does not entertain the thought that it can contain everything.”

This is a metaphor for the disappearance of egoism and possessiveness, by which you proceed to indestructible concentration.
