This is a word coined by Harvard Professor Edward O. Wilson, to describe the feeling of oneness with nature. It occurs when someone actually goes out of their selfish shell to understand nature, ending up loving nature instead of oneself. Narcissists destroy nature, they feel it is not a perfect reflection of themselves. Only by accepting nature and others as wonderful and uncontrollable, only then will a Narcissist join nature and humanity.
"Narcissism heals itself away from loneliness into creation: in our narcissism we wound nature and make things that cannot be loved, but when our narcissism is transformed, the result is the love of self that engenders a sense of union with all of nature and things."
