Shri Matsyamurti. From Tantra Song by Franck André Jamme, Siglio Press, 2011:
The “illustrious fish,” the little blue form that some eccentrics call “the little blue tongue.” One of Vishnu’s ten incarnations descending into the night of our dark world, yet under the seal of energy (the multi-colored spiral, thus having the power to sport all aspects of manifestation, all taste, all color). As if this energy, slightly drunk on its own richness, and turning in reverse, agreed to be guided—in time without time of a painting, by a god become fish.
