Question: How is it possible to develop the Supreme-Enlightenment Mind?
Huang Po: Bodhi [enlightenment or enlightened mind]* means nothing to attain. Even now, just as you allow thought to arise, you get nothing. Thus, realising that there is absolutely nothing to attain is the Bodhi Mind.
The realisation that there is nowhere to abide and nothing to attain is the Bodhi.
Therefore, Shakyamuni Buddha [the original Buddha, also known as Gautama Buddha] said ‘…there was really no Dharma [teaching or method] by means of which the Tathagata [the Buddha] attained Supreme Enlightenment…’
