Central to Shinnyo-en is the belief, expressed in the Mahāyāna Mahāparinirvāṇa Sūtra, that all beings possess Buddha-nature, a natural, unfettered purity that can respond creatively and compassionately to any situation in life.
[citation needed] In May 1936, Shinjō Itō was ordained by Daisōjō and Chief Abbot Egen Saeki at Sanbō-in, a temple of the Daigo school of Shingon Buddhism.
Formally registered in 1948 under the Religious Corporations Ordinance (Japanese: Shukyo Hojinrei, enacted in 1945) the name changed to Sangha of Truth (Makoto-Kyodan) with Shinchō-ji as its Head Temple.
The first Shinnyo-en Sanctuary outside Japan was inaugurated on March 2, 1971 in Mililani, Hawaii, followed by the dedication of temples in Honolulu (1973), San Francisco (1982), Taiwan (1985), France (1985), Los Angeles (1990), Italy (1990), Belgium (1991), Hong Kong (1992), U.K. (1994), Germany (1994), Singapore (1994), and Australia (1999).
In an interview conducted by the Tricycle magazine, Shinso Ito stated:[11] People who are interested in traditional Buddhist training are always welcome, but volunteer activities provide an additional avenue for Shinnyo-en to contribute to the wider secular community.
The Three Practices (三つの歩み, mittsu no ayumi) are:[12] Concretely, this means abiding by the principles of the Teachings, participating in volunteer activities, and donating small sums of money.
A sesshin involves receiving guidance from a 'Spiritual guide' (霊能者, reinōsha, medium), a person who has been specially trained and cultivated the Shinnyo spiritual faculty (霊能, reinō').
Its purpose is to enable participants to identify and transmute karmic impediments, develop their Buddha nature, and cultivate permanence, bliss, self and purity, i.e., enlightenment.
After three years of classes and fulfilling various requirements, including passing a written test and assessment of everyday practice, they are granted priestly ranks (僧階 sokai) and become dharma teachers.
"While most traditional Buddhist fire rituals focus on personal purification and awakening, the Shinnyo-en ceremony is dedicated to awakening people to their innate compassionate and altruistic nature, transcending all boundaries of age, gender, nationality, ethnicity, and religious tradition, and directing the positive energy of the ceremony outward with the hope that all people can live in a world of hope and harmony.
[citation needed] Traditional ceremonies, derived from Shingon Buddhism—many of which can be traced back to ancient Vedic and Hindu ceremonies—are an important aspect of Shinnyo Buddhist practice.
Prayers for ancestors and departed souls, such as the Lantern Floating ceremony, and O-bon (Sanskrit: Ullambana), are believed to also help cultivate kindness and compassion within practitioners.
[18] With the wish of creating cultural harmony and understanding, Her Holiness Shinso Ito, Head Priest of Shinnyo-en, officiated the inaugural Lantern Floating Hawaii ceremony on Memorial Day, 1999.
