Start meditating for short periods.
The best way to start a meditation practice is simply to start meditating. You’d be surprised at how difficult this can be. We often procrastinate until we find the perfect time. Don’t wait. Start immediately.
Find a quiet place where you can sit for a few minutes without being disturbed. Close your eyes and begin following your breath. Focus your attention on the sensation of the air passing through the tip of your nose. Count your breaths one through five silently in your mind. When you get to five, simply start over again. When you get distracted, immediately bring your attention back to your breath, and continue counting. The counting helps you stay focused.
After a few minutes, stop counting and begin observing the entire breathing process mindfully. When you get distracted, gently bring your attention back to your breathing.
Start with about a 10-minute session, then work your way up to about 20 minutes or more. It may be a challenge to sit still in the beginning, but it will get easier as your mind settles down over time.
