The mind is the root from which all things grow. If you can understand the mind, everything else is included.
Regardless of what we do, our karma has no hold on us.
Not thinking about anything is Zen. Once you know this, walking, sitting, or lying down, everything you do is Zen.
Everything sacred, nothing sacred.
To seek is to suffer. To seek nothing is bliss.
All the suffering and joy we experience depend on conditions.
