It is the nature of Knowledge, like Ki or a river, to flow.
Those who stand between the source and the sink may chose to profit from the flow in one of two fundamental ways: either by encouraging the flow or by restricting the it.
When the knowledge is meant to flow, chose to be one who encourages the flow, not one who restricts it. Align your path with that flow, not against it.
Moreover, be wary of those who you encounter who would restrict the flow---or your path. They are decidely un-aiki.
