Amida Buddha, and recite the nembutsu." (Master Rennyo)
Indeed, to have the sense of urgency in liberating yourself from death and rebirth is a sign of health on the Buddhist path. To wait, to feel that you have enough time for spiritual evolution its a delusion, the gravest delusion Mara, the demon, can give to you. And it is such a sweet delusion! How nice it is to spend your time thinking you are always learning and evolving!
