If your mind is happy then you are happy anywhere you go.
When wisdom awakens within you, you will see Truth wherever you look.
Truth is all there is.
It's like when you learned how to read, you can then read anywhere you go.
Meditation means the mind is turned back upon itself. The mind stops all the thought-waves and the world stops. Your consciousness expands. Every time you meditate you will keep your growth.
Regarding this Dhamma, it is not something that we can simply talk about or take another's word for it. We need to develop meditation so that the understanding arises clearly within oneself. It is not the case that merely by listening to another's explanation our defilements will disappear. When we gain some understanding we need to chew on it again so that we see it for ourselves with certainty: paccattam.
Everything is based on mind, is led by mind, is fashioned by mind. If you speak and act with a polluted mind, suffering will follow you, as the wheels of the oxcart follow the footsteps of the ox. Everything is based on mind, is led by mind, is fashioned by mind. If you speak and act with a pure mind, happiness will follow you, as a shadow clings to a form.
Meditation is not something restricted to times of formal seated meditation; it is most fundamentally an attitude of being-a resting in and as being. Once you get the feel of it, you will be able to tune into it more and more often during your daily life. Eventually, in the state of liberation, meditation will simply become your natural condition.
