To enter by reason means to realize the essence through instruction and to believe that all living things share the same true nature, which isn't apparent because it's shrouded by sensation and delusion.
BodhidharmaThe essence of the Way is detachment. And the goal of those who practice is freedom from appearances.
BodhidharmaDon't hate life and death or love life and death. Keep your every thought free of delusion, and in life you'll witness the beginning of nirvana, and in death you'll experience the assurance of no rebirth.
BodhidharmaNot thinking about anything is zen. Once you know this, walking, standing, sitting, or lying down, everything you do is zen. To know that the mind is empty is to see the buddha.... Using the mind to reality is delusion. Not using the mind to look for reality is awareness. Freeing oneself from words is liberation.
