The essential distinction between Śamatha and Vipaśyanā
(Calm Abiding and Insight)
When thoughts arise, they are neither forcefully stopped nor suppressed.
By simply resting naturally, attachment and grasping toward mental objects gradually dissolve into the very nature of mind.
This is called Śamatha (Calm Abiding).
To see the essence of mind directly and nakedly —
its true nature: emptiness, unborn, the Dharmakāya itself —
this is referred to as Vipaśyanā (Insight).
If one wishes to engage in any form of meditation,
one should first cultivate calm abiding.
Thereafter, genuine insight will arise profoundly and naturally.
It is essential to persevere continuously,
without losing focus, diligence, or effort.
Gradually, the union of calm abiding and insight
will naturally unfold within one’s experience.
