Being is accessible to you now as your own deepest self, your true nature. But don't seek to grasp it with your mind. Don't try to understand it. You can know it only when the mind is still. When you are present, when your attention is fully and intensely in the Now, Being can be felt, but it can never be understood mentally.
Eckhart TolleDifferent ages have certain approaches, which may be more effective for one age and no longer effective in another age. The world that we live in now has much greater density to it; it is much more all-pervasive. And when I say "world," I include the human mind in it. The human mind has grown even since the time of the Buddha, 2,500 years ago. The human mind is more noisy and more all-pervasive, and the egos are bigger.
Eckhart TolleSpace has no "existence." "To exist" literally means "to stand out." You cannot understand space because it doesn't stand out. Although in itself it has no existence, it enables everything else to exist. Silence has no existence either, nor does the unmanifested.
