Practising Zen and Tibetan Buddhism

I suspect there are not that many people who are practising both Zen and Tibetan Buddhism at the same time. But I am doing just that. I would like to believe that I am combining elements of both traditions in a way that suits my spiritual needs, and at the same time does not make the practice into a mumbo-jumbo spiritual mixed cocktail. I think I know how to distinguish the practices and not to "corrupt" any practice in any way. I don't add my own flavour, so to speak. I find that each practice fulfills a part of my spiritual need that may not be adequately be fulfilled by another practice. By the guidance of my Tibetan Buddhist gurus and Zen teachers, ... and others... I hope to complete my spiritual journey in this lifetime.
