Different 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 TollePay attention to the gap - the gap between two thoughts, the brief, silent space between words in a conversation, between the notes of a piano or flute, or the gap between the in-breath and the out-breath. When you pay attention to those gaps, awareness of 'something' becomes - just awareness. The formless dimension of pure conciousness arises from within you and replaces identification with form.
Eckhart Tolle
