The four wise truths is an adaption of the four noble truths of Buddhism.
The first wise truth is that the unawakened life is full of suffering. Suffering here is mental pain, stress, or unease.
The second wise truth is that the cause of suffering is the three mind traps, which are attachment, aversion, and unawareness.
The third wise truth is that if you eliminate the mind traps, you eliminate the suffering.
The fourth wise truth is that the way to eliminate the mind traps is through a threefold process of morality, meditation, and wisdom.
