Meditation is the direct way to "know thyself". This is the case regardless of one's belief, tradition, metaphysical theory etc. Just sit and observe. Put aside all explanations and directly see what is happening within. Simple, not easy.
Revelations and connections emerge through a quietened my-and state, in a form of collected unity and through non spoken ways.
Yet there is wisdom and inspiration imparted within the stillness, that surpasses the intellect.
