Mr. Lương Sĩ Hằng was born in Qui Nhơn, Việt Nam on December 20th 1923, the youngest of eight children. Mr. Tám's continuing ill-health during his youth eventually forced him to leave school. He began his business career working with his father. He was a successful entrepreneur and also had business interests in a movie theatre and motor boats. At the age of 28, he married Trần Tân, his devoted wife to this day.

At the age of 33, Mr. Tám became highly motivated in his search for the inner self. He met Mr. Đỗ Thuần Hậu (Master Tư) through a mutual acquaintance. Under the guidance of Master Tư, Mr. Tám began to practice the Vô Vi method in order to attain enlightment and soul liberation. He was the assistant marketing manager for Getz Brothers Inc., a US trading company in VietNam before 1975. Despite heavy work responsibilities, he devoted his weekend to lecture on spiritual matters.

When Communists took control of South VietNam on April 30th 1975, Mr. Tám was suspected of being a supporter of the previous regime. He was sent to a reformation camp in Vũng Tàu for 13 months. Whilst in prison, Mr. Tám practiced acupuncture and was able to cure many fellow immates in conditions which were unhygienic and lacking medical supplies.

Mr. Tám's mission of spreading the knowledge of spiritual guidance, occasioned his departure from VietNam on November 3rd 1978. He reached the Republic of Philippines on November 6th. At the Fabella Refugee Camp in Manila, many fellow refugees were helped by influential Filipino people who had received acupuncture treatment from Mr. Tám.

In 1979, Mr. Tám settles permanently in Canada. Despite his old age, Mr. Tám continues to travel the world visiting practitioners and imparting the Vô Vi meditation method. His message of peace and resignation clarifies and lights the path towards deliverance.
