Through eyes we can identify shape.
Through ears we can identify depth.
Through nose/scent we can identify vibration.
Through mouth/taste we can identify values.
Through skin we can identify existence.
It would be nice if you have something you can smell during meditation.
How to live in the present moment. Uncertainty is always created by someone. Try to create your own if/then theory in order to be clear about your life. Just like the people who had to reinvent their restaurants to become only take out restaurants to predict tomorrow and some point in the future. They changed their mind, gave up everything, followed their gut, and made decisions and goals while relying on hope, sweeping their floors, cleaning their walls, and redesigning their patterns to continue sharing their establishment with others.
In this moment, practice how we can generate the laws, rules and tools out of our own experience with the if/then theory to make this moment stable.
