Shinran = the Great Tantric Masters

"Although I too am within Amida's grasp,
 Passions obstruct my eyes and I cannot see him;
 Nevertheless, great compassion is untiring and illumines me always."
 — SHINRAN SHONIN

I think the quote above sums up beautifully the way relative truth relates with ultimate truth and is the same quitessential message of the great tantric masters. No doubt about it. Indeed, his knowledge is equivalent to the Great Tantric Masters. The more I read his works the more I think his deep wisdom is second to none.
