Let-go is not achievable. But we can approach it from another direction: The Willingness to See.
We can see within, we can allow an inner eye to open. Some have called this inner eye the Third Eye, a label that is only a metaphor for the willingness to see.
As we journey deeper into meditation, any effort to avoid seeing the inner nature of things constitutes struggle. Trying to See is a form of struggle.
We can allow ourselves to embrace what is, it is our nature to watch. Watching could not be easier. What makes it difficult is the idea that we need to succeed. That too can be watched.
Any ideas of a right way or a wrong way will empower the “I”, and that leads back into the pit of effort. Simply watch. You will See–if you are willing.
