Inside and Outside Work by Zen Master Wu Bong

Zen Master Seung Sahn used to say that there are two kinds of work. Inside work and outside work. Inside work means keeping a non-moving mind and outside work means helping all beings.

Being concerned only about inside work is not correct Zen practice. Only inside work means nirvana and peace of mind only for me. Including outside work into our individual practice means living with a direction for others and not only for me. How can we share with others?
