I am posting this quote vom Yoga Vasishta because it perfectly fits the topic of this month. Unfortunately I do not have the exact references, so I am asking anyone who has it to let us know and possibly fix the translation if it is not correct (dear readers, please check the comments).
O Rama, you have reached that state of satva and your mind has been burnt in the fire of wisdom. What is that wisdom? It is that the infinite Brahman is indeed the infinite Brahman; the world-appearance is but an appearance whose reality is Brahman. Page 328
Because the substratum (Infinite Consciousness) is real, all that is based on it acquires reality, though the reality is of the substratum alone. The universe and all beings in it are but a long dream. To me you are real, and to you I am real; even so the others are real to you or to me. And, this relative reality is like the reality of the dream-objects. Page 71
Whatever there is here which exists and functions here is real to the self and not to another who does not perceive it and is unaware of it. Therefore, all these creations and creatures that exist within the field of the energy of consciousness are true to the perceiving self and are unreal to the non-perceiver. All the notions and the dreams that exist in the present, past or the future are all real, because the self which is the self of all is real. Page 574
One can say that this world-appearance is real only so far as it is the manifestation of consciousness and because of direct experience; and it is unreal when it is grasped with the mind and the sense-organs. Wind is perceived as real in its motion, and it appears to be non-existent when there is no motion: even so this world-appearance can be regarded both as real and unreal. Page 88
