It’s all very simple. Stub your toe, it hurts. Hug someone, it feels warm. Feel the space in which you sit, it is open and unencumbered.
Direct perception is simple, accessible to everyone right now. Does it mature into intuition? Yes, but that’s immaterial; a huge boulder on the shoreline will slowly dissolve into sand, but right now there is rock and sea.
The direct participation in the hurt toe declares that existence is raw and rough and often quite painful on any and many levels. The warmth of an embrace is a direct participation in the unity that underlies all existence. Letting yourself experience the spaciousness of the space around you will lead to the space within, not to mention open one in that moment. Direct perception is direct participation. It’s very simple.
