Zen is a way to achieve it through Zen. The wise master said: neither Zen nor wisdom, nor wisdom nor Zen.

Zen alone, no wisdom, no way. Only wisdom, without meditation, can not see the Tao. So, don't look at double luck, look at the road.

Such as yoga theory.

Therefore, from Zen to wisdom, from true wisdom to seeing Tao. Then Zen virtue is achieved.
