To be mindful is to be in the present moment. Mindfulness is not a practice, it is an outcome of meditation.
Practicing mindfulness involves effort. You’re thinking about and concentrating on being in the present moment. Thinking and concentrating use effort, and are exhausting. You’re trying hard to be present.
Vedic Meditation is easy. You close your eyes and repeat a mantra. Your mind settles down and your body rests deeply. You automatically release stress and tiredness.
When you come out of meditation, you are spontaneously aware and in the present.
