Normally the mind is a whirlwind of thought, and meditation is a practice that calms this down and helps us develop a peaceful state of mind. Not only is our mind busy thinking, we’re usually thinking about the past or the future. We’re either reliving old dramas or imagining what could happen tomorrow or in ten years and trying to plan for it. We usually aren’t experiencing the present moment at all. We can’t change the past, and the future is always ahead of us — we never reach it, have you ever noticed? So, as long as this process continues, our mind never comes to rest. The mind can never just settle down and feel at ease.
When we practice sitting meditation over time, we get better at catching our thoughts and releasing them. Gradually the mind begins to settle naturally into a resting state. This is great because it allows us to be fully present in our lives. When we aren’t being pulled into the past or future, we can just be right here, where we actually live. To be in the present moment simply means to be awake and aware of yourself and your surroundings. That‘s the beginning of peace and contentment.
