Knowing that is Buddha
There are a lot of ways to be happy and a lot of ways to be unhappy in this world. Probably more ways to be unhappy than happy - an happiness connected to causes and conditions is unstable, impermanent and carries the seeds of unhappiness within it.
Frankly that, as an existential condition, would suck – if it described the boundary of what we are. But, happily, it doesn’t.
This whole world with its happy unhappy is a bit of a bit of straw blown off the barn roof into divine mystery.
Being in its authenticity - an unadulterated openness spontaneity is untouched by birth and death ..... that is the true boundary-less-ness of our condition.
Knowing that is Buddha. Not knowing is suffering. Here the "knowing" is always in the existentiality of our wholeness ... body, speech, mind, qualities, activities .... untrammeled unutterable essence and luminous playful nature.
Wisdom is as much in your toes as it is in your brain. In fact toes and brain are both inside wisdom. The whole body of appearance is the form body of a Buddha. Known as it, lived as it ..... in all its complexity, heartbreak, beauty, sorrow, joy.
The body of appearance - a single whole is the form body of the Buddha. The pervasion of appearing by uncreated luminosity prior to all appearing is the bliss body of the Buddha. An unadulterated awareness unqualified by attributes, substance, appearance, non-appearance, being or non-being is the wisdom body of the Buddha. Your own body speech and min are just these when known in their truth.
