The orientation of this group is the shifting over time of one’s identity and sense of self from the personality or ego to one’s deeper and ultimate nature—Being. As this experiential knowledge is integrated, one’s life becomes a lived and fulfilling expression of our realization. In the contemporary spiritual path of Diamond Approach to Inner Realization, this becomes possible through bridging traditional divisions between the sacred and the mundane, the spiritual and the worldly, inner realization and our psychology. While utilizing elements from depth psychology, the enneagram where applicable, and traditional spiritual knowledge and practices, it is a fundamentally new method for engaging in the process of radical personal transformation. A webinar with Sandra Maitri giving a good overview of the Diamond Approach is available on our webinar page.


The format of the group will include presentations of the teaching, personal inquiries done with others, private inquiry sessions with assisting teachers, process groups, and movement exercises. Through these different modalities, students will be exploring themselves in a deep and experiential way. Because the teaching builds on itself, it is expected that students will participate in all retreats, making them up when unable to attend. For those of you from the enneagram community, please note that the enneagram will be a subset of this work and not the central subject.

This group has closed. We are no longer accepting new students into the group. However, if you've been a member of another Diamond Heart group either now or in the past and have previously had the material, you may apply to this group.

The Diamond Approach


The Diamond Approach is a path of wisdom, an approach to the investigation of Reality and a method of working on oneself that leads to increased understanding and liberation. It connects us with our spiritual nature, bringing it into our life. The Diamond Approach represents a new paradigm in human/spiritual knowledge and understanding. It encompasses existing spiritual knowledge as well as presents new dimensions of our deepest nature. At the same time, it helps us understand the relationship of the entire human psyche—ego, personality, and soul—with its fundamental nature and shows us how these dimensions are inseparable.

The Ridhwan School

The Ridhwan School is the home of the Diamond Approach teaching. It was founded in 1976 by Hameed Ali, who writes under the name A.H. Almaas. It is an inner Work school devoted to the realization of True Nature. The Ridhwan School makes teachings available to the public through various programs, trains teachers, and supports the publication of teaching material through books and webinars.

As an example, a schedule is attached here.



Tuition for each retreat is $1273 per person, which includes one private session. Additional private sessions may be arranged at the retreat for $110 each.


Once you’ve attended your first retreat and have agreed to become a member of DHR6, we expect that you will plan to attend all following retreats in their entirety. The material presented at each retreat builds during the course of the retreat and it is important to participate as fully as possible. 


We realize that sometimes life circumstances arise and you may have to miss a retreat. If this happens, you will be required to make up the material that was covered in that retreat by listening to the recordings and doing the exercises. The tuition for missed retreats is $800. Once you have paid the missed retreat tuition, you will be given access to the recordings so that you can make up the material before the next retreat.



Once you are accepted to DHR6 as a new member, and if you want to attend one retreat to find out whether this is the place for you, you are welcome to do that.  If you are sure that you want to continue, we ask that you listen to the retreats you have missed and do the exercises in a timing that works for you. The fee for past retreat recordings is $525 per retreat (half the original retreat’s tuition.)  If this is a concern or hardship for you, and if you are making up many previous retreats, please contact Carol via the form below.



(Prices includes three meals each day)


As this is a retreat group, we strongly encourage you to stay at the retreat venue. This will support your process and the overall field of the group. If you feel this will not be possible for you, we ask you to contact our admin to discuss your reasons why. 



All fees for both tuition and food/lodging will be payable online via PayPal or credit card. Once your lodging intentions are known by the admin, you will receive an invoice and where to send payment. 




If accepted into DHR6, you will become a member of the Ridhwan Foundation. The Foundation is the governing and administrative organization that is home to the Diamond Approach.


All students of DHR6 will need to pay dues to the Ridhwan Foundation.  All students of the Diamond Approach, once their groups are established, are required to pay annual dues, as this is part of our legal obligation. These dues help to support the administrative, communications, and legal processes necessary to run the organization. If you would like more information about them, visit the website. Ridhwan dues will be due in January of each year. The baseline dues are $150 a year.



Once your Information Statement is on file and your Ridhwan dues have been paid, you will have access to the Ridhwan Portal.   On the Portal, recordings of each retreat will be available, as well as other information about activities that are available to you.


If you are a current new student, a staff member from the Ridhwan Foundation will send you an email about setting up Portal access. Once that is complete, the process to access recordings is:

  • Sign into My Portal

  • Under My Groups, click Diamond Heart Retreat Group 6

  • At the top right, click Teaching Library

  • Click the name of the retreat, and the recordings will populate
