If you want to start the Practice of Meditation, then nothing can stop you.
1. Find a place.
You can be home, or at a park, or the beach, even on the bus, as long as it's peaceful and pleasant for you. Also try to find a favorite place when at home, and meditate there frequently to build up the energies.
2. Add extras
Extras are just that - extra. Optional but can be very beneficial. Candles, music, healing crystals, pillows, even a friend. The more people meditating together, the stronger the energies will be.
3. Sit comfortably, or lie down.
Your back needs to be straight for chakra alignment, so if lying down, no pillows under the head. If seated, cross legs indian style, or place both feet flat on the floor.
4. Relax
Close your eyes, and start to release tension from all parts of the body. Work from the head down, or feet up. Shake the feet and hands, roll the head around a few times slowly, bang you knees together, raise and lower the shoulders until you can feel very loose and relaxed.
5. Breathe
Breathing is the single most important part of meditating There are many styles, but start with the most simple. Inhale through the nose, and exhale through the mouth. Do this as slowly as you can tolerate. Count for both. Start with a count of 3 or 4, and gradually build up. Breathing also helps to keep the thoughts away.
6. Clock yourself
For the beginning, it's best to get some idea of how long you sit in meditation. A kitchen timer is the best tool. Make your goal 15 minutes once a day, until you reach the point of being able to meditate as often or as long as you want.
7. Meditate daily
We all know what it's like to start a new project, and then find reasons to stop. In meditation, there is no good reason to stop. It's a discipline of the highest order. Meditate daily no matter what, even if you don't feel like it. The energies and benefits build up, and drop by drop, you will understand why you wanted to start in the first place.
Now you know how to Meditate. So get started. Enjoy. Grow and heal. And welcome to the club.
