The Dharma is something you need to come and see for yourself. It is experiential. Meditation holds the keys. We can unlock the door of reality. Among them are the Three Doors of Liberation. Emptiness. Signlessness. Aimlessness. These are the keys.
What are these Three Doors of Liberation?
Along with this, we take a deeper look at several pairs of opposites (in the context of signlessness).

birth and death
being and nonbeing
coming and going
sameness and otherness

We can liberated from our fear, our anger, our despair.
The story of the flame is quite humorous and enjoyable.
