Mindfulness should be continuous and can be practised in four postures as well as daily activities.
Sometimes It's not appropriate to sit, make the most of the intensity of Bangkok while you're there, it's a riot!
"Right effort is effort with wisdom. Because where there is wisdom, there is interest. The desire to know something is wisdom at work. Being mindful is not difficult. But it’s difficult to be continuously aware. For that you need right effort. But it does not require a great deal of energy. It’s relaxed perseverance in reminding yourself to be aware. When you are aware, wisdom unfolds naturally, and there is still more interest." - Sayadaw U Tejaniya
