NHƯ LÀ

Tranh: Ánh Mắt Mùa Thu -  Xuân Thi

NHƯ LÀ

  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

  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 " **

* A Dedicated Poem by Zen Master Thich Nhat Hanh to venerable Thich Thien Minh

TIẾNG CHUÔNG CHÙA PHƯỚC SA

Cảnh Chùa Phước Sa - ảnh Y-Minh Nguyen

TIẾNG CHUÔNG CHÙA PHƯỚC SA

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.
