There is really no difference between matter, mind and Spirit. They are only different phases of experiencing the One.
Swami VivekanandaAn intellectual, heartless man never becomes an inspired man. It is always the heart that speaks in the man of love; it discovers a greater instrument than intellect can give you, the instrument of inspiration.
Swami VivekanandaThe mind generally takes up various objects, runs into all sorts of things. That is the lower state. There is a higher state of the mind, when it takes up one object and excludes all others.
