And what I am talking about includes but is not at all limited to physical pain. There are physical, emotional, and spiritual layers to the pain that arises by necessity within anyone who treads a spiritual path.
With the passage of time and through repetition practice shows you that facing and experiencing pain is one of the main sources of wisdom. It is essential to acknowledge, respect and know pain as a principal source of spiritual nourishment that leads to growth and wisdom. As James Hillman said “the wound is the eye”, meaning that your pain is the means by which you see inside your self and thus win soul knowledge.
