LINEAR LIFE is the way that life is perceived and understood conventionally.
Each life is like a line. It stretches back through the past and forwards to the future.
Each line is separate from the next.
LATERAL LIFE is the true nature of things.
All there is, is the present. There is no past or future. No line stretching backwards or forwards... just this... here... now.
An analogy would be to compare life to a screen and its changing scenes.
There are no lines of separation... just the seamless arising of what is.
