"After overcoming the challenges of emotion and worry and establishing a very solid foundation, the rest of one’s perceptions will be as quick and natural as the passing of the sun and the moon. I hope everyone can practice on the foundation very seriously! There are a lot of high levels of practice, but they are based on a high level of preliminary practice. It has been said many times that a high level of practice without a foundation is like building a palace on a frozen lake. Once the ice and snow melt, it will no longer exist."
Karzang Rinpoche
