Bodhidharma 5th Century AD. Indian Prince brought Buddhism to China
ďTo find a Buddha all you have to do is see your nature. Your nature is the Buddha. And the Buddha is the person whoís free: free of plans, free of cares. If you donít see your nature and run all day around looking somewhere else, youíll never find a Buddha. The truth is, there is nothing to find. But to reach such understanding you need a teacher and you need to struggle to make yourself understand. Life and death are important. Donít suffer them in vain. Thereís no advantage in deceiving yourself. Even if you have mountains of jewels and as many servants as the sand along the Ganges, you see them when your eyes are open. But what about when your eyes are shut? You should realize then that everything you see is like a dream or illusion. If you donít find a teacher soon, youíll live this life in vain. Itís true you have the Buddha-nature. But without the help of a teacher youíll never know it.Ē
True spiritual teachers are emanations of the absolute form of the Buddha, the Dharmakaya, and are thus essentially the Buddha himself. Being fully realized beings themselves, only they can help us realize our true nature..
