The houses, kin, and lands are the attachments of the outer life, the fixed structures and relations of personality that hold a person's sense of self in place, and to forsake them for the name's sake is to loosen one's grip on these identifications for the sake of the awakening presence within. What is released in the outer is returned a hundredfold in the inner, because every attachment surrendered frees a corresponding measure of energy and awareness that had been bound up in it.
The hundredfold is not more property but the multiplied life that floods in when consciousness is no longer tied to its possessions and roles. Letting go of the outer holdings opens the deathless awareness that owning them concealed.
Houses and lands: the fixed structures of the outer life that anchor a person's sense of self
Brethren, father, mother, wife, children: the relations of personality, the identifications that bind awareness to the outer self
Hundredfold: the multiplied inner life released when attachment to the outer holdings is loosened
