Stillness is your essential nature.

Humans are potentially capable of living in a state of consciousness compared to which normal wakefulness is like sleeping or dreaming.

Neither concepts nor mathematical formulae can explain the infinite.

It is precisely through the onset of old age, through loss or personal tragedy, that the spiritual dimension would traditionally come into people's lives. This is to say, their inner purpose would emerge only as their outer purpose collapsed and the shell of the ego would begin to crack open. The emphasis shifts from doing to Being, and our civilization, which is lost in doing, knows nothing of Being. It asks: being? What do you do with it?

The thinking mind can be so noisy that it cannot relate to stillness. It doesn't even recognize it and certainly can't remember it.

What you think of as they past is a memory trace, stored in the mind, of a former Now. When you remember the past, you reactivate a memory trace -- and you do so now. The future is an imagined Now, a projection of the mind. When the future comes, it comes as the Now. When you think about the future, you do it now. Past and future obviously have no reality of their own. Just as the moon has no light of its own, but can only reflect the light of the sun, so are past and future only pale reflections of the light, power, and reality of the eternal present. Their reality is "borrowed" from the Now.

An amazing realization is in the present moment there is only what is, but there are no problems. And if your attention remains in the Now, you no longer inhabit a world of problems. Challenges you may still face, but they come to you in the space of Now.
