In theory, there are said to be eighty-four thousand approaches, or entrance doors, in Buddhism. The large number is to indicate that, in fact, anyone can start wherever they are. To climb Mount Everest, you could set out from the traffic jams of a Parisian suburb or from the lush greenery of a Nepalese valley. The goal is the same, but the ways you might travel are different. In the same way, on the spiritual path we all have to start at the point where we find ourselves, each with a different character, set of dispositions, intellectual and belief structure. Everyone can find the particular means tailored to their needs, allowing them to work on their thoughts, gradually set themselves free from the yoke of negative emotions, and finally to perceive the ultimate nature of the mind.
