Getting butter from milk is only possible because milk already
contains cream. No one ever made butter by churning water. The
prospector looks for gold in rocks and not in wood chips. Likewise, the
quest for perfect enlightenment only makes sense because the buddha-nature
is already present in every being. Without that nature, all efforts
would be futile.
