2. Osho Lao Tzu library, Poona. Interior from the central room, Ramakrishna. In this room the most valuable parts of the collection are shelved. Books are on glass shelves behind sliding glass doors and with mirrors placed behind the books. Two books of the same size or colour are not to be placed next to each other, so the effect is that of waves going up and down, adding a lighter impression of the packed shelves than usually seen in libraries.
