Beliefs & Suffering
Any and all beliefs gives rise to suffering. Believing in any thought or sets of thoughts, inevitably gives rise to suffering.
Existence is always more than and different from our perception of it. And even more so from any belief, even if it is derived from our perceptions. A belief is always limited.
When Existence does not correspond to the thought we believe in (which is inevitable), then there is naturally suffering.
And this suffering is the most exact guidepost to the thought we believe in. To where we are stuck.
