What can be learned about love if one considers it as an energy that is the result of self-awareness? In his essay On Love, Caleb Gattegno applies this question to various aspects of love, examining topics such as Love-Attachment, Romantic Love, Friendship, Universal Love and Outgrowing Egocentricity. On Love was written by Gattegno as a personal exploration and as a means of creating a space for reflection and discussion with his readers.
