The Spirit is an ethereal entity. It requires to establish a connection with the Energy in order to get energized and maintain its subtlety. Turning away from the Energy hardens the spirit. It becomes unappreciative of the metaphysical Reality.
The spiritual Heart is like a mirror, from which the Eternal Energy reflects. By neglecting the spirit, we cripple our spiritual abilities and become oblivious of the Truth. It is not the eyes, but the hearts that go blind.
Spirituality means acknowledging the existence of the spirit and seeking its reformation and enlightenment. When the spirit is reformed, the purpose of our existence is achieved. We can see beyond the physical and becomes cognizant with the Truth.
Spirituality is not the name of a philosophy or a theory, but a practice. It is the easiest and the simplest exercise you may have known. You can practice spirituality irrespective of your color, race, religion, gender or age.
By doing the spiritual exercises like Sufi Breathing that I have described in my book, you can restore your spirit to full health. Spirituality gives you immense satisfaction and consummates the purpose of our existence.
