Where one sees another, one hears another so long as there are two, there must be fear, and fear is the mother of all [misery]. Where none sees another, where it is all One, there is none to be miserable, none to be unhappy. [There is only] the One without a second. Therefore be not afraid. Awake, arise, and stop not till the goal is reached!
