迷人的

I understand it will take longer for a registered lettered to arrive at its destination, is that right?

挂号信送到目的地要慢一些，对吗？

Dukkha vedana in the old position is usually very easy to see when yogavacara is working; but sankhara dukkha (pain carried into the new position) is very difficult to see – because the new position usually appears to be a happy one.

明觉起作用的时候很容易体会到旧姿势中的苦苦，但行苦（变换到新姿势所残留的苦）却很难体会得到→因为新姿势通常令人觉得舒服。
