A Quote by Huangbo Xiyun on oneness, immanence, and insight

Hold fast to one principle and all the others are identical. On seeing one thing, you see all things. On perceiving an individual’s mind, you perceive all mind. Glimpse one truth, and all truth is present in your vision, for there is nowhere at all that is devoid of the Truth. When you see a grain of sand, you see all possible worlds, with all their vast rivers and mountains. When you see a drop of water, you see the nature of all the waters of the universe.
