I second this. I have been practicing Isha's meditation technique 'Shambhavi' which I learnt at Inner Engineering program. No matter what, I set aside 45-60 mins everyday for doing basic yoga and meditation for the last 5 months.
Firstly, daily yoga made me very aware of my posture(work/excercise/sports) and it has helped me gain discipline in life.
Secondly, the inner peace after meditating lasts very long and it mellows down my entire day. I am more aware of my emotions and thoughts. I am very grateful for this.
