This sutra is the reverse of the preceding one. The true yogi neither feels aversion or desire. He is balanced between these pairs of opposites. Hate causes separation, whereas love reveals the unity underlying all forms. Hate is the result of concentration upon form and of a forgetfulness of that which every form (in more or less degree) reveals; hate is the feeling of repulsion and leads to a withdrawal of the man from the object hated; hate is the reverse of brotherhood and therefore is the breaking of one of the basic laws of the solar system. Hate negates unity, causes barriers to be built and produces those causes which lead to crystallization, destruction and death. It is energy used to repudiate instead of to synthesize and therefore runs counter to the law of evolution. Hate is really the result of the sense of personality and of ignorance plus misapplied desire. It is almost the culmination of the other three. It was the sense of personality and of extreme ignorance coupled with desire for personal gain which produced hatred of Abel in the heart of Cain and caused the first murder, or the destruction of a brother's form. This should be carefully considered, [137] for hate in some degree, aversion to some extent, is present in every human heart. Only, however, when it is entirely overcome by love or the sense of unity will death, danger and fear pass out of the ken of the human family.
