The most important characteristic of the Eastern world view – one could almost say the essence of it – is the awareness of the unity and mutual interrelation of all things and events, the experience of all phenomena in the world as manifestations of a basic oneness. All things are seen as interdependent and inseparable parts of this cosmic whole; as different manifestations of the same ultimate reality. The Eastern traditions constantly refer to this ultimate, indivisible reality which manifests itself in all things, and of which all things are parts. It is called Brahman in Hinduism, Dharmakaya in Buddhism, Tao in Taoism. . . .
The Sanskrit term for meditation – samadhi – means literally 'mental equilibrium.' It refers to the balanced and tranquil state of mind in which the basic unity of the universe is experienced:

Entering into the samadhi of purity, (one obtains) all penetrating insight that enables one to become conscious of the absolute oneness of the universe.
