That's a bug chunk of time, so I rounded up a few resources for getting started that require just 10-15 minutes of sitting:
- This 25-minute, "Mini Anapana for All" audio is a great introduction from Goenka; the first 15 minutes are the important part. It suggests a regular practice of 10-15 minutes per day, morning and evening.
- The 10-min "Group Sitting" audio will also suffice.
- "Brief Instructions for Sitting Meditation" from Audio Dharma is a 5-min quick intro.
