The endless variety of sights and sounds, experiences and feelings. The unceasing stream of thoughts and ideas, memories and wish lists.
We rely on mind as the basis of experience, even if we train the mind it is still mind on which we rely. Relying on mind, we cannot escape mind.
It is the ground that we walk on, no matter how much we train, how fast we can run or how far, all we experience is a temporary rush and a fleeting high. We can never expect to fly.
You need to create a distinction between mind and the nature of mind, between ordinary mind and naturally occurring timeless awareness.
You can chart and explore the earth for ages, and you should. But you also need to see the view from space.
