Meditation practice is like the gym for the mind, a time we practice cultivating inner wisdom. This site focuses on the practices of mindfulness and compassion. Meditation can be practiced formally. It is recommended to dedicate time each day (even a few minutes) to awareness training, to opening the heart, to listening to the body. You can practice with or without guidance. When starting a new practice, using guiding meditations can be quite supportive. There are many teachers out there. Try out a few to find the styles that resonate with you. While many practice in a seated position, you can practice while standing, laying down or walking. Always choose what is most supportive to you at that time.
Also, meditation can be practiced informally. Go to Supportive Practices for examples.
When I first began meditating, I tried so hard to do it right. Every time my mind wandered, I would get frustrated and felt as if I would never be able to meditate. I am hoping to help you avoid this situation. Meditation is not something we achieve (are you listening my fellow perfectionists?). It is a means to training the mind to become more aware, to open our hearts to gently be with all of our experiences. In essence, meditation is a way to wake up to our lives.
There are many ways to meditate, but the most common is breath focused meditation. This is a common way to anchor your attention as you develop your skill of concentration, a foundation of mindfulness. However, there are other ways to anchor attention like in the body or sound.
