Null Meditation

Just sit there and don't do anything.
Contrasting with the Dhyana Meditations,
you don't visualize any particular yantra.
Instead, you allow images to appear.

Checklist

  1. Mindfulness Meditation

All life is only a set of pictures in the brain, among which there is no difference betwixt those born of real things and those born of inward dreamings, and no cause to value the one above the other.

Yield and remain whole
Bend and remain straight
Be low and become filled
Be worn out and become renewed
Have little and receive
Have much and be confused

Therefore the sages hold to the one as an example for the world
Without flaunting oneself - and so is seen clearly
Without presuming oneself - and so is distinguished
Without praising oneself - and so has merit
Without boasting about oneself - and so is lasting

Because they do not contend, the world cannot contend with them
What the ancients called "the one who yields and remains whole"
Were they speaking empty words?
Sincerity becoming whole, and returning to oneself
