suspending the five senses
Your mindfulness becomes deeper when you limit your 5 senses to meditate. If you can reduce in one way or another what you can see, hear, smell, taste and feel for 10 minutes, that would be a good starting point. Remain seated, either on a chair or directly on the floor (You don’t necessarily have to sit cross-legged.), continue breathe deep and slowly. Then, try to stay in the mindfulness with the ‘suspension of the 5 senses’ for a longer period of time.
