悟りを開きたいという欲望も煩悩ではないかと心配する人がいますが、誰のために悟りを開きたいかによります。自分だけの幸福を望むのなら悪い欲望ですが、他人に幸福をもたらしたいと望むのなら良い欲望です。仏教では、他人に幸福をもたらすために悟りを開きたいと望む心を「菩提心」と呼び、最重要視しています。

Some people worry whether their desire of attaining enlightenment may be also disturbing mind. However, it depends on their motivations. If their motivations are for the happiness of themselves only, it is a bad desire, but it is a good desire if their motivations are for the happiness of others. In Buddhism, the desire to attain enlightenment for the happiness of others is called "Bodhicitta" and is considered as the most important factor.
