What exists in truth is the Self alone. The world, the individual soul and God are appearances in it. Like silver in mother-of-pearl, these three appear at the same time and disappear at the same time. The Self is that where there is absolutely no 'I thought'. That is called 'Stillness'. The Self itself is the world; the Self itself is 'I'; the Self itself is God; all is Siva, the Self.
