Paradox and polarity often play a significant role in mystical experiences, awakenings and non-dual realizations.
In these experiences, one realizes the illusory nature of duality and the interconnectedness of all things, breaking down the traditional dichotomies of good and evil, self and other, etc.
Inquiring into the polarities of one's thoughts, beliefs, emotions, coping mechanisms and emotional programs through practices like this can break down the dualistic thinking patterns and reveal what is residing just under the dualistic illusion revealing the true mystical experience, awakening, and non-dual realization.
