Hsuan Hua, also known as An Tzu, Tu Lun and Master Hua by his Western disciples, was a Chinese monk of Chan Buddhism and a contributing figure in bringing Chinese Buddhism to the United States in the late 20th century.
Buddhism regards all living creatures as being endowed with the Buddha nature and the potential to become Buddhas. That's why Buddhism teaches us to refrain from killing and to liberate creatures instead.
If you have no obstacles in your own mind, then outer obstacles will not hinder you or cause you worry.
When silence reaches an ultimate point,
the light penetrates everywhere.
