If you focus the rays of the sun through a lens, they can burn cotton or a piece of paper; but, the scattered rays cannot do this act. If you collect the dissipated rays of the mind and focus them at a point, you will have wonderful concentration.
SivanandaAlways do good to others. Be selfless. Mentally remove everything and be free. This is divine life. This is the direct way to Moksha or salvation.
