modem Buddhism and its followers

How Vajrayana arose from Mahayana is clearly indicated in the works of Vajrayana literature. The human soul bent upon the attainment of the highest knowledge progresses from the lower region of earth to the higher, till all flesh disappears and it rises above the world of the Kama to the world of rupa or form. The mind bent upon Bodhi passes on through a variety of forms till it reaches the highest of the rupa heavens, still Bodhi is not attained. It goes higher and higher to the region where form doesn't exist. This is called the Arupaloka or the formless world. In its progress higher and higher in this formless world it rises to the top and vanishes in the infinite void. That's the idea of Nirvana of the mahayanists, but the vajrayanists at this stage mystically conceives the existences of Niratma Devi at the top of the formless (Arupa) heaven. She seems to all intents and purposes a metaphor for the infinite void. From the top of the formless world The mind bent on the Bodhi leapes into the embrace of Niratma Devi and enjoys something like the pleasures of the senses, and disappears in her, as Salt disappears in water. Thus Vajrayana is a curious mixture of mysticism, philosophy and sensuality. The sensual part of this doctrine made it exceedingly attractive and soon superseded the dry mantrayana and the difficult Mahayana.
