If the mind is at ease, if it's at peace then it will be naturally aware. As you keep doing it, the breath diminishes, becomes softer. The body becomes pliable, the mind becomes pliable. It's a natural process. Sitting is comfortable: you're not dull, you don't nod, you're not sleepy. The mind has a natural fluency about whatever it does. It is still. It is at peace. And then when you leave the samādhi, you say to yourself, 'Wow, what was that?' You recall the peace that you've just experienced. And you never forget it."
