I’ve found walking meditation to be very helpful. It’s like an intermediary between samatha breath meditation and mindfulness in everyday life. Sometimes I think it’s under-emphasized because it’s more straightforward than breath meditation, and therefore less likely to be asked about. During the periods of time where I did half an hour of walking meditation per day, I definitely felt like I noticed a difference. In fact, posting this is reminding me that I need to make time to start doing that again 🙂
Loving-kindness meditation is also very helpful. I don’t have experience doing lengthy loving-kindness sits, but I like to do 2-5 minute meditations every day either before or after a samatha meditation sit. These can have a wonderful effect on the mind and heart, especially when experiencing stress.
