Soma and fire are identical in Vedic literature. The ancient Hindus saw fire both as a symbol of Agni and as an emanation of the inner libido-fire… The Vedic definition of soma as ‘seminal fluid’ confirms this view.
Jung argues that Soma and Agni are psychologically equivalent as expressions of libido-fire, and that Soma’s Vedic definition as seminal fluid supports its interpretation as psychic dynamism.
