Meditation, you know, comes by a process imagination. You go through all these processes purification of the elements - making the one melt the other, that into the next higher, that into mind, that into spirit, and then you are spirit.
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.
Swami VivekanandaWe should cultivate the optimistic temperament, and endeavour to see the good that dwells in everything. If we sit down and lament over the imperfection of our bodies and our minds, we profit nothing; it is the heroic endeavour to subdue adverse circumstances that carries our spirit upward.
Swami Vivekananda
