"Unless a man is spiritual he is not alive yet. But to move from the biological realm to the spiritual realm is very difficult, arduous. It is the greatest challenge there is. It is the greatest quantum leap – from the body to the soul, from the material to the immaterial, from the visible to the invisible, from time to timelessness, from out to in. It is arduous.

"Buddha, in this sutra, says there are twenty difficult things. These twenty difficult things can become twenty steps of the challenge. These twenty difficult things are not to make you beware of them; Buddha is talking about these twenty difficult things not to make you avoid them – it is an invitation, it is a challenge.

"These twenty himalayan peaks are just a challenge for you... a great invitation. Don′t remain in the valley. The valley is very secure, convenient, comfortable. You will live comfortably, you will die comfortably. But you will not grow. You will only grow old, but you will not grow.

"Growth happens only when you are accepting a challenge. Growth happens only when you start living dangerously. These twenty things are indicative of how one should live." Osho
