Th way of isolate being would be the choice to live as close to ones essential nature as possible.
Our essential nature is revealed to us by a process of letting go of what is extraneous and superficial in ourselves and our lives.
Letting go occurs in various realms: the material, the social, and the personal.
To let go in the material world would be to let go of unnecessary possessions and the want of them.
To let go in the social realm would be to become free of the influence of other individuals, and of the social group and culture.
To let go within ones own personality would involve dropping the nonessential, whether artifice or vanity or affectation or self-indulgence, etc. and cleansing ourselves of emotions that color and distort our memories, experience and thinking.
