Meditation is the ability to be able to focus on an idea, a saying, a situation, a prayer, or on the great knowingness in the Universe. Some say prayer is you speaking to God and that meditation is God speaking to you. What it is does not matter.
What matters is that when you meditate, little changes happen. You become more at ease and peaceful. Life seems to flow more smoothly. All the changes are good. Osho says that you can meditate five minutes a day and receive benefits.
What is frustrating you today? What is making you feel sad or angry? Are you feeling hurt? Try a little quiet time with yourself.
