Brotherhood means to stand and work in the same spirit.
When you are a child, then brotherhood means to be born of the same parent or parents.
But the older one gets, and the more mature one grows; the more one enters into the living gout of one’s destiny, and the more one senses and fulfill one’s destiny, then the less brotherhood remains a being born of the same parents and becomes a standing and working in the same spirit. Spiritual homogeneity is true brotherhood.
The same thing with sisterhood.
