The only colours used are black and white, which are in themselves colourless, yet the black ink can be seen in five tonal gradients.

That absence of colour is a colour in itself; the pure at heart entails real sentiment; yet one could lose one’s direction in colours.

The pure black can replace the rest of the colours; it can even surpass the usual colours for representation of the true picture.

Unrestrained form allows the expression of truth and real sentiment.

Any figurative depictions are only incidental, what matters is a genuine representation of the pure form.

One stroke can surpass a thousand strokes; applying no technique can even surpass the application of numerous techniques.

An un-sculpted natural form may surpass sculpting from pre-conceived shapes to give form, thus the natural form gives way to the true form.

Shapeless, strokeless, colourless, only nothingness.

Only by freeing oneself into the realm of nothingness can the true form be fully realised.

純一色彩黑白本無色墨分五色

無色即色純真具真情五色令人色茫

直指玄色去五色不假五彩見真相

不拘形象是揚真相真情

不管像不像是真像

千筆不如一筆千法不如無法

千刀不如無刀自然無感即為真成

無形無筆無彩無無無

真無乃現真象也
