The Blessed Buddha once said:
In the seen is merely the process of seeing...
In the heard is merely the process of hearing...
In the sensed is merely the process of sensing...
In the thought is merely the process of thinking...
So knowing, you will not be connected 'with that'...
So disconnected you will not be absorbed 'into that'...
So neither with that, nor into that 'You are not' created by that sensation!
When there is no 'You' inferred or conjectured by that very experience,
then 'You' are neither 'here', 'there', 'both', 'beyond' nor 'in between'...!
On realizing the importance of this incident the Blessed One exclaimed:
Where neither solidity, fluidity, heat, nor motion find any footing,
there no sun, moon nor star ever shines. There is neither any light,
nor is there any darkness! When the Noble, through stilling of all
mental construction, through quieting of all mental formation, directly
experiences this, then is he freed from both form and formlessness,
then is he released from both pleasure and all pain ..."
