Douglas Adams claimed the answer was 42. But there are other interpretations.

There are also certain temporary states of being when we can sense meaning. I call these “awakening experiences”.

Usually these experiences occur when our minds are fairly quiet and we feel at ease with ourselves. When we’re walking in the countryside, swimming in the ocean, or after we’ve meditated or had sex.

At such times there is a sense of “rightness” about things. We can look above us at the sky and sense something benevolent in it, a harmonious atmosphere. We can feel a kind of radiance filling the landscape around us, emanating from the trees and fields. We can sense it flowing between us and other people – as a radiant connection, a sense of warmth and love. We feel glad to be alive and feel a wide-ranging sense of appreciation and gratitude.
