by Swami Sivananda
Meditation is the keeping up of the one idea-be it of Nirguna Brahman, Saguna Brahman, image or an abstract idea. It follows concentration where all the rays of the mind are focussed on to a single thought.
Ultimately even this single thought gives place to Awareness-just awareness and illumination-where all problems dissolve themselves.
When you enter into deep meditation, you will have no consciousness of your body or surroundings. You will have equanimity of mind. You will not hear any sounds. The consciousness of egoism also will gradually vanish. You will experience inexplicable joy and indescribable happiness. Gradually reasoning and reflection give place to awareness.
If you can meditate for half an hour, you will be able to engage yourself with peace and spiritual strength in the battle of life for one week through the force of this meditation. Such is the beneficial result of this meditation. As you have to move with people of different natures in your daily life, get the strength and peace from meditation and you will have no trouble and worry then.
Sit down with a composed mind. Assert your mastery over the body and mind. Plunge deep into the chamber of your heart and enter into the stupendous ocean of Silence. Listen to the voice which is soundless.
