Although the scriptures contain a lot of practices on emptiness, in the end, whether it is investigating the feeling of happiness, the world outside, or ourselves, what we want is a moment of realization — a very strong sense that all of these things are non-existent, empty, and illusory. The more powerful this feeling is, the better. At that time, we must not “disturb” this feeling or state of mind but maintain it to the extent possible.

- Quote from The Four Seals of Dhama, "The Practice of Realizing Emptiness"
