About Meditation by Swami Sivananda

Meditation bestows self-confidence, courage, serenity and inner spiritual strength. When you meditate, shut the doors – the doors of the senses. During meditation you are never left without an unseen guide. He will help you. Without meditation, where is peace? Without peace, where is happiness? Meditation is the food for the soul. Meditation is the key to knowledge. Therefore, meditate, meditate.
