There are people who have renounced all possessions but have a bigger ego than some millionaires. If you take away one kind of identification the ego will quickly find another. It ultimately doesn't mind what it identifies with as long as it has an identity. Anticonsumerism or antiprivate ownership would be another thought form, another mental position, that can replace identification with posessions. Through it you could make yourself right and others wrong. As we shall see later, making yourself right and others wrong is one of the principal egoic mind patterns, one of the main forms of unconsciousness. In other words, the content of the ego may change; the mind structure that keeps it alive does not.
