Tranh: Ánh Mắt Mùa Thu -  Xuân Thi

  Tặng chị XT

Chị con người trung trực
Bản lĩnh và rất hiền
Đôi mắt đẹp như tiên
Nhưng có khi mắt cỡ

Luôn từ tâm giúp đỡ
Kẻ nghèo khó tật quyền
Chị đa tài lại siêng
Nhan sắc và hiếu thảo

Dáng thon thon hoàn hảo
Tựa Khánh Hà mê ly
Chị thanh thản Xuân Thi
Đong đầy tấm lòng thiện

Ở chị luôn biểu hiện
Hoan hỷ và buông tha
Tham sân si tránh xa
Chơn như y Diệu Thiện

THIỆN MINH - An Eternal Guiding-light

The late Most Venerable Thich Thien Minh - from
THIỆN MINH - An Eternal Guiding-light
  In the memorial of 35th passing of the late Most Venerable Thich Thien Minh

The late most venerable was one of the Zen pillars of Vietnamese Buddhism
His vows were to liberate suffering of all beings with his wisdom, courage and compassion
He was a symbol of the national heroism with extraordinary leadership talents
He was from the village of Bich Khe, Trieu Phong, Quang Tri
In 1933, he became a novice monk at the age of 12 years old.
And after many hard years of studying and practicing the teachings of Buddha,
At the age of 27, he became the president of Da Lat Buddhist Association and a Dharma teacher
He was an exceptional monk, high-regards with senior leadership ranking within the Buddhist Revival movement.
He helped build and strengthen the infrastructure of the Unified Buddhist Church of Vietnam from Southern providences to the Highlands.
He then established of many Buddhist schools and Buddhist Bodhi academy of Nha Trang
As well as founded many Vietnamese Buddhist Associations (GDPT)
His teachings transform many generations of Vietnamese youth to dedicate their lifetime for the greater good.
The venerable fought for religious equality and social justice by non-violent means
He was the symbol of wisdom, conscious, courage, sacrifice, and peace
He was a resilient leader, indomitable and intelligent
He held many positions from Director General for Youth
To the Acting President of the UBCV’s Institute for the Dissemination of the Dharma.
He traveled and shared Dharma from East to West
His endless works and efforts were for the welfare of all Vietnamese people, Dharma, and for the country of Vietnam.
The venerable was in and out of jail in three different governments
And eventually passed away mysteriously in a harsh condition of the Communist prison
On October 17, 1978
In the state of shocking, touching, loving and respecting of a great honorable Master
He was the symbol of Bodhisattvas in modern Vietnam Buddhist era
A great frontier, a compassionated Buddhist teacher
He was a "White cloud floating in the vast sky..."*
"Like the moon shining upon Mount Lanka
Like the perfume rising from the Prajna lotus " **

Cảnh Chùa Phước Sa - ảnh Y-Minh Nguyen


Trăng rằm thanh tịnh quá
Lung linh với ngàn sao
Như Phước Sa thuở nào
Trong câu kinh nhịp mỏ

Cùng trầm hương theo gió
Tiếng chuông chùa ngân xa
Sâu lắng như thiền ca
Gọi người mau tỉnh thức.
