Before anything can come into being there must be somebody to whom it comes. All appearance and disappearance presupposes a change against some changeless background.
The mind covers up reality without knowing it. To know the nature of the mind, you need intelligence, the capacity to look at the mind in silent and dispassionate awareness.
What prevents you from knowing yourself as all and beyond all, is the mind based on memory. It has power over you as long as you trust it; don’t struggle with it; just disregard it. Deprived of attention, it will slow down and reveal the mechanism of its working. Once you know its nature and purpose, you will not allow it to create imaginary problems.
