Some Zen from Jingjue in his preface to the ‘Masters of the Lanka’:
The path to awakening
Is impossible to map.
It is lofty but has no ‘above’;
Impossible to reach its limit.
Deep but has no ‘below’;
Impossible to measure its depth.
So large it encompasses heaven and earth,
So tiny it enters where there is no gap;
This is why we call it the path.
From ‘The Spirit of Zen’ by Sam Van Schaik, Yale University Press, (2018), ISBN: 0300221452
These teachings on early Chan (Zen), ‘The Masters and Students of the Lanka’, were discovered in a sealed cave on the old Silk Road in modern Gansu, China, in the early twentieth century.
They are more than a thousand years old.
