There are two attitudes, one, you see everything as perfect, another is finding various imperfections. One is called Pravriti, when you’re engaged in action; nivriti, when you retire from action. Often, we are not okay with the way things are around us and then we get worked up. You don’t get rest because when something is not right, your whole tendency is to act towards it and this causes tension.
In Bhagwad Gita it’s said that the intelligent one knows what is the right attitude for everything. You know when to meditate or go inwards and contemplate. When you have the attitude that everything is okay or perfect then the mind settles down. Meditation is deep rest that helps you become very sharp and alert, and when you find imperfections around, you can correct them. This is the ability of the human mind, this shift from not okay to everything is okay is a skill in itself. That is what sadhna does to you when you’re able to switch off from everything and attain deep rest through meditation. Then again you have to switch from inaction to action.
