A lot of what we're taught in Religion, in yoga, even by our Gurus and master teachers is 40% the principle, 60% experience. Now this wouldn't be terrible if the experience were our own and not that of someone else. For many, those that preach it have come to it through heartache, pain and tough lessons. It is then, when the practice makes sense, falls into place and the message can be absorbed.
But to teach finding peace to someone who's core has not been shaken. To teach believing in abundance when one has never experienced lack and to teach love when one has never felt hate, is hard.
Until you have the battle scars, the wounds, the scabs can you truly understand the 'point of it all'? Without contrast can you really feel sympathy, compassion? Without the lesson can you really understand the message?
I believe that we take from our teachers the knowledge of what their road has taught them, but it is up to us to figure our place. To understand if this path is for us and if what the teachings teach can help us find clarity.
My teacher says that Karma is misunderstood, that it's not about do this and gain brownie points, do that and lose. It's about working off karma from the past, learning lessons and becoming better. Your fate is already written and what is happening is already foretold. There isn't anything you can do or not do to stop the course of what's to come. Whether you believe this or not, or it makes you happy or depressed the point is LIVE. DO. BE. EXPERIENCE. CREATE. LEARN. REPEAT.
Trust your path.
