When we concentrate we focus our attention on one particular thing. But when we meditate we feel that we have the capacity deep within us to see many things, deal with many things and welcome many things all at the same time. When we meditate, we try to expand ourselves, like a bird spreading its wings. We try to expand our finite consciousness and enter into the Universal Consciousness where there is no fear, jealousy or doubt but only joy, peace and divine power.
Meditation means our conscious growth into the Infinite. When we meditate what we actually do is enter into a vacant, calm, silent mind and allow ourselves to be nourished and nurtured by Infinity itself. When we are in meditation we want only to commune with God. Now I am speaking in English and you are able to understand me because you know English well. Similarly, when we know how to meditate well, we will be able to commune with God, for meditation is the language we use to speak with God.
