Tantra has many meanings and is a vast subject.
Here are the words of three different masters, not necessarily on tantra itself, but on spirituality in general.
‘The state we call realization is simply being one’s self, not knowing anything or becoming anything. If one has realized he is that which alone is and which alone has always been; he cannot describe that state, he can only be that. Still it is a wonder that to teach this simple truth, there should come into being so many religions, creeds, methods, and the disputes among them. Oh the pity! Oh the pity! Ramana Maharshi
‘I am a cup caught in the hand of Love. If you dont believe me, look in my eyes. Or better still……. listen to my heart.’ Rumi
One day a devotee asked Swamiji, ” What is mind control?” Throwing a flower in the air Swamiji answered, “See if my mind goes after the flower and gets glued to it, that is the mind going out of control. If I dont’t allow my mind to go out of control and keep it here – that is mind control. Simple !” Sri Shivabalayogi Maharaj
