In order for us to achieve enlightenment, what do we need. We need insight wisdom. Basically we need to recognize, understand or realize the truth. Which is according to the Buddhadharma – which can be achieved by understanding the selflessness of phenomena and the selflessness of a person, or an ego, or self. That kind of insight wisdom can only be established if you have a steady, or a stable, unwavering, unshakable foundation of shamata or shine, calm abiding. I don’t know how you translate that. Basically that is what you need to achieve, you need to establish the shine.
