Nature's Finer Forces: The Science of Breath and the Philosophy of the Tattvas

Rama Prasad's Nature's Finer Forces is an early and influential English-language presentation of tattva philosophy, the Hindu tantric scheme of elemental subtle principles, written within the late nineteenth century Theosophical milieu that first popularized many South Asian esoteric concepts for Western readers. As a primary artifact of that transmission, it is valuable for understanding how tattva theory entered Western occultism and influenced later systems including some Golden Dawn practice. It is not a rigorous philological translation of the underlying Sanskrit tantric sources, and specialists in Hindu tantra have noted that Prasad's presentation reflects the interpretive framework of his own Theosophical milieu as much as the source tradition's own technical usage, so it documents a reception history rather than settling the tradition's own doctrine.
