Any action giving a feeling of joy and a sense of performing duty is meditation. It is not necessary to go to Haridwar or Rishikesh to meditate, or even sit at one place for meditation. With such an attitude, even when a person fights for his country, he is in meditation. Observe great singers, dancers and artists; when they perform, they tune themselves becoming instruments in the hands of the Lord, free of any ego or pride. This state of joy is meditation in action.
When we express deep feelings of love and respect towards anyone we love and revere, in thought, word or action, we are in meditation.
We experience meditation in understanding the true nature of the Universe, through the intellect or buddhi. The philosophy of division sees differences, creates hatred, violence, misery, and agitation in the mind. This cannot give us peace and quietude. The Vedanta philosophy of Oneness views the whole cosmos and every thing in it as pervaded with Ishwara. Through touching, seeing, smelling, hearing and tasting we commune with God alone. See the whole Universe as one family – Vasudhaiv kutumbakam. In this understanding of Oneness, we are in a state of meditation.
