Hameed Ali, under the pen name A.H. Almaas, has written more than twenty books. They are brilliant illuminations of humanity's spiritual nature and potential. Unsurpassed in their knowledge, understanding and accessibility they form the basis for and are a record of a new and genuine wisdom tradition. They are a uniquely profound contribution in service of humanity's deep (though often unconscious) yearning for self knowing and self realization; for living in peaceful harmony with onself and with the world.
Below I have suggested four of them. These can give you an introduction to The Work. They may give you a sense that The Work is or is not interesting or appealing to you. You may get a sense of what I contemplate teaching and guiding whoever shows up and sticks around.
The Inner Journey Home (Parts 1-4). This book offers an understanding that the human individual is a soul, a living spiritual presence. It describes and offers a profound perspective on the soul's potential for development and maturation.
The Unfolding Now. This one sheds light on the path's main method by which the soul may unfold and fulfill its potential. It speaks of the "primary awakening" of The Work by which one can come to know oneself as a spiritual presence fundamentally unconstrained by time and space.
Space Cruiser Inquiry. This book explains and gives examples of Diamond Approach's central practice of "open ended inquiry".
Diamond Heart Book 1. This book clarifies some of the basic concepts of the path.
For those who would rather listen than read the suggestion is: The Diamond Approach available from SoundsTrue.com. It is lengthy, but a highly illuminating interview with Hameed, the founder of the Diamond Approach.
