Slowly slowly each act of your life should turn into a meditative act. Then there is a possibility to attain to enlightenment. Then you can sit also because that too is an act, but you are not specifically identifying sitting with meditation — that too is a part. Walking you meditate, working you meditate, sometimes sitting silently you meditate, sometimes lying on your bed you meditate… meditation should become your constant companion.
And this meditation that can become constant companion is a very simple thing, I call it witnessing. Just go on witnessing whatsoever is happening. Walking you witness, sitting you witness, eating you witness yourself eating, and you will be surprised that the more you witness things the better you can do them because you are non-tense, their quality changes. You will also note that the more meditative you become every gesture of yours becomes soft, non-violent, has a grace in it. And not only you will notice it, others will start noticing it.
