A little enquiry shows that we never actually experience a past or a future, because we continually live in a now. This is all we experience, whether we are a child in age or an elderly person. This now is really out of time and it is certainly out of the past, because the moment you attempt to grasp the past it is not there, there is only the now. The same applies to the future. In that sense, existence in time is illusory. In the higher mystic experience there is complete stillness and no movements of the mind in thought, and there is also a lapse of the feeling of time and an entry into a purely timeless condition. This condition is a true condition for happiness, for it confers an indescribable peace of mind which is the only kind of happiness we can expect to experience on this earth.
