The reason we require a fixed 'good-will donation' in the first instance is: because it shows that the proposer (you) is serious about wishing to be part of a greater whole…to the benefit of all LiberExtoL’s healing members. This modest investment symbolizes your commitment to being involved in a program of both assisted and self-help.
By this generous act you are recognising there has to be an exchange of energy…since, in reality, there is no such thing as a complete vacuum. Before water can fill the bottle, the bottle must first give up its air…and vice-versa. In this way the air and water complement one another’s existence, thereby justifying the bottles existence as a vessel--to ‘give’ and ‘receive.’
