When the mind becomes still

This morning i went to a 2 hour meditation session ,given by a friend of mine. There was a time i was meditating daily ,once in the morning and once in the evening for quite some years. I left the practice and practice my own being of awereness. But somehow for quite some time i hear the call of starting it up again. Alas there are some many distractions in life like for instance , practicing music and some other hobbies. Anyway the session went fast and it was like i have done it yesterday . It means once ou mastered that skill it never goes away. I must say afterwards i felt a stream of energy through my whole body.
