The opening of the plane is usually prepared in the course of meditation after it has begun, when the descent has stabilized and reaches a certain magnitude (depth). Usually it looks like a switch of vision from what we see around to the consideration of some place, world, object or formation, substance and light, moving or stationary, etc.

For the practitioner, discovery occurs spontaneously or in response to aspiration, impulse, manifestation of the will to see, find a solution, etc. After the plane is opened, conscious action is possible in it.

Moments of discovery and action are what usually happen after a lot of trying or patiently striving for them. Successful and unsuccessful attempts gradually accumulate experience and develop a specific perception of the moment of possibility of action.
