Chan is the combined result of wisdom and compassion. Chan also means to make use of Dharma in daily life. Chan is a kind of subjective experience from the within. It can only be understood through actual practice. Real Chan cannot be expressed by any words or languages. However, Chan requires words and phrases to be the medium for instruction and practice. Take, for example, the analogy of the index finger and the moon. You can point to the moon with your index finger so that others can see the moon. It is obvious that your finger is not the moon, even when we are able to see the moon through your pointing. Yet many people confuse the finger for the moon itself, meaning that they take language and symbols to be the real thing.
