Are you having a hard time building a consistent daily meditation practice? Rather than worrying about how long your sessions should be, focus on really trying make daily meditation a habit.
Start out with the expectation of just sitting or walking for 5-10 minutes a day. Trust me when I say from experience that doing 5-10 minutes of meditation a day is much more fruitful then doing 30-60 minutes once or twice a week.
When you build up the habit of every day sitting, even for 5-10 minutes, you are creating a skillful habit that will bring you and others great benefit. As you start to see these benefits you will naturally have the desire to meditate longer periods and the seeds of your initial practice will grow.
That’s not to say it will be easy, or that you reach a point where meditation is all sunshine and rainbows. Meditation is hard work and you will have your good and bad days, cycles of practice where you feel like a meditation master followed right after by cycles that make you feel less then a newbie, it’s all the nature of the practice, and it’s all worth it. Consistently practicing through the ebbs and flows is how it’s done.
Remember consistency breeds stability, start small and build a strong base that will lead you to peace.
