Masaharu Taniguchi began Seicho-no-Ie in 1930 not with a book but with a small magazine carrying the same name, meaning House of Growth. That starting point matters for understanding Seimei no Jisso, Truth of Life, the body of teaching this atlas cites under a single title even though Taniguchi himself never fixed it at one dated edition.
Rather than writing a single systematic treatise and leaving it fixed, Taniguchi kept publishing, expanding and republishing his teaching across many volumes over the following decades as the movement itself grew from a small magazine readership into an international religious organization. Truth of Life became the general name under which that expanding body of teaching was collected and reissued, closer in spirit to an ongoing serialized doctrine than to a single closed scripture handed down once and never revisited.
That growth by accretion is itself characteristic of how Taniguchi worked. He continued teaching and writing for decades after Seicho-no-Ie's founding, and followers today generally encounter Truth of Life as a multi volume set rather than a single slim founding pamphlet, a structure this atlas's own citation record makes explicit by naming no single publisher or publication year, since the citation is to a living, continually expanded teaching rather than to one fixed printing.
