I started reading the
'Purification of the Heart' by Hamza Yusuf. I loved it from the very first page, that is the acknowledgments section :-)
The introduction is also great. It gives interesting information about the spiritual heart, of which we believe that it is centered in the physical heart.
Excerpt: " The heart is centered slightly to the left of our bodies. Two sacred languages of Arabic and Hebrew are written from right to left, toward the heart, which, as some have noted, mirrors the purpose of writing, namely to affect the heart. "
Excerpt: " We know that the heart starts beating before the brain is fully fashioned, that is, without the benefit of a fully formed central nervous system. The dominant theory states that the central nervous system is what controls the entire human being, with the brain as its center. Yet we also know that the nervous system does not initiate the beat of the heart, but that it is actually self-initiated, or, as we would say, initiated by God. We also know that the heart, should all of its connections to the brain be severed (as they are during a heart transplant), continues to beat. "
In the introduction Hamza Yusuf concludes that as opposed to (mainly) western views that the brain is at the center of our being, it is in fact the heart that is the center of our being, the human consciousness, and conscience.
He says that when we look at the world and ask ourselves wholeheartedly from where all this injustice, hatred, etc. comes that we will find that they are all rooted at or caused by people with diseased hearts.
But the heart is designed to be in a state of calm, it longs for peace and harmony. To insure such a state, we have to examine our hearts, look for diseases and try to cure them. This book contains the description, causes, and cures of 25 diseases of the heart. Enjoy !
