Bhallataka seed rasayana

Kernels of well-ripened, purified bhallataka nuts are eaten on a schedule: a quarter, a half and three quarters of a kernel on the first three days, one to five kernels on days four to eight, then five more each day up to a hundred and five fewer each day back to one. The text says one who eats ten thousand kernels in this way is freed of all disease and becomes ageless.
