Buddhism
Buddhism is like a thorn used to remove another thorn. When the thorn is out, there is no more use for Buddhism. You can throw it away. Similarly, spiritual teachers are useful to point one towards the Truth and to stimulate one's mind; but when one has found the Truth, they are no longer needed. The traveller who finds his road blocked by a river will use a raft to cross it. Upon reaching the other shore he will not carry the raft on his shoulders to continue his journey; he will abandon it as something which has become useless.
Concepts can destroy concepts, words can destroy words, tools can dismantle tools. By using them in this way, we can end all untruth. That which is left we call Truth. Meanings destroy meanings, leaving us with the Almighty Meaning.
Before contact with Buddhism, a bowl is a bowl and tea is tea. While studying Buddhism, a bowl is no longer a bowl and tea is no longer tea. In the end, one becomes enlightened, and once again a bowl is a bowl, and tea is once again tea. The dismantling is all done, and one can forget Buddhism.
This is why it is said: "There is a Buddha for those who do not know what He really is. There is no Buddha for those who know what He really is." The millions upon millions have mistaken the tool for the reality, the finger pointing at the moon for the moon itself.
