Space is beyond color or shape.It doesn’t take on color, black or white: it doesn’t change. Likewise, your mind, in essence, is beyond color or shape. It does not change because you do good or evil.
The darkness of a thousand eons cannot dim The brilliant radiance that is the essence of the sun. Likewise, eons of samsara cannot dim The sheer clarity that is the essence of your mind.
Although you say space is empty, You can’t say that space is "like this". Likewise, although mind is said to be sheer clarity, There is nothing there: you can’t say "it’s like this".
Thus, the nature of mind is inherently like space: It includes everything you experience.
Stop all physical activity: sit naturally at ease. Do not talk or speak: let sound be empty, like an echo. Do not think about anything: look at experience beyond thought.
Your body has no core, hollow like bamboo. Your mind goes beyond thought, open like space. Let go of control and rest right there.
Mind without projection is mahamudra. Train and develop this and you will come to the deepest awakening.
