About Us

Luminous Mind Sangha’s mission is to foster awakening and its embodiment in worldly life, through the application of authentic, rigorous Buddhist and modern practices.

Tina Rasmussen, Ph.D., Guiding Teacher

Tina’s warm style, bright clarity and supportive presence helps students recognize their deeper nature, both on the cushion and in daily life. She has a decades-long commitment to cultivating her own and others’ deep spiritual unfoldment while functioning in an embodied, worldly life.

Dr. Rasmussen learned to meditate in 1976, at age 13. In 2003, after many years of practice in Buddhist and modern non-dual traditions, she was drawn to undertake an intensive year-long solo retreat during which a profound awakening to Reality occurred. In 2004, Tina took refuge with Tibetan Dzogchen teacher Tsoknyi Rinpoche, and was initiated into the Nyingma lineage. In 2005, Tina attended a 2-month retreat with Burmese meditation master Ven. Pa Auk Sayadaw, who ordained her as a Buddhist nun and gave her the dharma name “Ayya Pesala.” During the retreat, Tina became the first Western woman to complete the entire detailed Samatha path in this lineage.

As an offering of gratitude to the dharma, Tina, along with Stephen Snyder, wrote the book, Practicing the Jhanas, which was later published by Shambhala Publications. In 2007, Tina became the first Western woman authorized by Ven. Pa Auk Sayadaw to teach.

After these life-changing experiences, at first Tina felt a strong pull to become a “cave yogi” and turn away from householder life to abide in the peace of Truth. However, over time, the possibility functioning from realization while living in the dynamism of the modern world became a more compelling life’s path. Tina then began participating in the Diamond Approach, a contemporary wisdom path designed for householders, that integrates the psychological and the spiritual into one continuum for living “in the world but not of it.” Tina has been studied by Yale Neuroscience Lab for research on the effects of meditation on consciousness and the brain, has been featured in “Awakening Women,” Non-duality Magazine, Conscious TV, Buddha at the Gas Pump, Buddhist Geeks, GuruViking, After Awakening, the Imperfect Buddha, Rick Hanson’s Wednesday Meditation, and others.

Dr. Rasmussen now leads retreats and offers spiritual guidance and mentoring to practitioners worldwide. She has a Ph.D. in human and organizational development, and worked as an executive coach and consultant in the business world for more than 25 years. She is also the author of several published books on humanistic business practices.

Jennifer Wheeler, M.A., Teacher-in-Training

Jennifer’s life is centered on discovering the most effective alchemy for waking up and living an engaged life in the world. In her life so far, this combines meditation, investigation, curiosity, and, most importantly, an unwavering commitment to truth.

Jennifer began meditating in 1998 and received her first formal instruction in 2001 at a Japanese Zen temple. She practiced subsequently in the Vietnamese Zen tradition, in which she was authorized as a lay Dharma teacher and then took ordination as a monastic. During that period, she also received a master’s degree in Buddhist Studies.

While training as a lay Dharma teacher, Jennifer found Tina and Stephen’s book “Practicing the Jhanas,” which ignited her passion for Samatha meditation. That led her to attend retreats with Tina and Stephen and with other lay and monastic Buddhist teachers.

After finding that not all her experience could be contained within the Buddhist tradition, Jennifer set out to explore other pathways, including Advaita Vedanta and the Diamond Approach, in which she continues to be a student. What she teaches has some of the flavor of each of these as it has been distilled through her own experience.

Jennifer has practiced many forms of meditation in addition to samatha: concentration and open awareness meditations in the Diamond Approach, the brahmaviharas of the Buddhist tradition, chanting and recitation, and movement meditations, among others. As her own path unfolds, she is exploring meditations that help to stabilize her realizations and support deeper and more ongoing access to the ground of being, including embodiment practices.

Currently, she sits daily, does group retreats and self-retreats and is in a multi-year teacher training program with Tina. Much of Jennifer’s spiritual exploration takes place in her home in a small town in South Carolina, where she stays close to the land and enjoys her neighbors, family, and the animals with whom she shares her life.

Marisa Mohrer, LMSW, MPH, Teacher-in-Training

Marisa (she/her) sat down to formally meditate in the midst of an overfilled graduate school schedule. As a therapist trainee in community mental health committed to reducing human suffering, she first learned about the clinical applications of mindfulness to support her clients. She was surprised when she began to experience meditation firsthand, and noticed the potent effects of concentration and compassion practice. In returning to the breath, Marisa gradually began to uncover an unexpected truth regarding reality and the human condition. After completing a dual Master of Clinical Social Work and Public Health degree at the University of Pennsylvania, she undertook a period of intensive silent meditation training.

In radical silence, Marisa grew intimate with the vast landscape of the human experience and with suffering. It was in this stillness that she, through meditative concentration, began to peel back the layers of engrained concepts that overlay a more fundamental reality. In learning to be fully present, she began to experience an absence of the ego structure. At that point, a boundlessness of reality opened up, shifting her identity as well as her perception of life and death. This experience galvanized her unwavering commitment to meditation, not only as a practice, but as a way of life. Upon leaving silent retreat, Marisa began the process of integrating this opening into daily life as a family therapist.

Marisa is a teacher in training under the guidance of Tina Rasmussen. Marisa aims to teach from the space of deepening embodiment of what she has come to experience through meditation. She hopes to point others, both directly and through Samatha and Non-dual practice guidance, to the heart of the human experience, that of Unity. It is here where we can experience that life is a seamlessly emerging and interconnected process, free of suffering.

The pillars of curiosity, compassion and concentration hold the potential to allow us to directly experience our undying True Nature. Marisa hopes to convey this to her students with clarity, joy and love.
