Buddha-Dharma Method of Vô-Vi Transcendental Science, that Mr. Đỗ Thuần Hậu (1883-1967) [also known as (aka) Mr. Tư] founded in 1942 in Vietnam, after a long period of searching the spiritual path. His successor is Master Lương Sĩ Hằng (spiritual name Vĩ Kiên, aka Mr. Tám), who continued to develop this meditation method throughout the five continents.

The Vô-Vi meditation is a practice that can be done in tandem with your ordinary and spiritual life. This means the practitioner is not required to follow any conditions, such as being a vegetarian, shaving one's head, not having a family, etc. You can continue to live your daily life normally; you just need to practice meditation and mentally chant the mantra the mantra of Nam Mô A Di Đà Phật diligently every day.
