Stay together friends. Don't scatter and sleep.

Our friendship is made of being awake. -- Rumi

To study the Way is to study the self. To study the self is to forget the self.

To forget the self is to be enlightened by all things. To be enlightened by all things

is to remove the barriers between one's self and others. --Dogen Zenji

 The One Heart Sangha is a multifaith community of Zen students who sit together on a regular basis to support one another in staying awake, moment-by-moment, to see and live our true nature, our at-one-ment with all.  One Heart Sangha exists to support the ongoing practice and compassionate presentce of its members. Our lineage is that of the White Plum Asanga which was established by Taizan Maezumi Roshi and draws heavily on the teachings of the Soto School of Zen, founded by Dogen Zenji in the 13th century.

Silver Spring Zendo/One Heart Sangha is a non-profit organization. 

We are affiliated with the Zen Peacemakers Sangha, founded by Roshi Bernie Glassman. Its members are individuals, groups and organizations dedicated to realizing and actualizing the interconnectedness of life.
