There is really no difference between matter, mind and Spirit. They are only different phases of experiencing the One.
Swami VivekanandaThe essential thing in religion is making the heart pure; the Kingdom of Heaven is within us, but only the pure in heart can see the King. While we think of the world, it is only the world for us; but let us come to it with the feeling that the world is God, and we shall have God.
Swami VivekanandaIf you want to have life, you have to die every moment for it. Life and death are only different expressions of the same thing looked at from different standpoints; they are the falling and the rising of the same wave, and the two form one whole.
Swami VivekanandaWhen the body is still healthy and diseaseless, When old age has not yet attacked it
Swami Vivekananda
