How to experience freedom and peace of mind in this complex daily life? I am bound by my duties and responsibilities very tightly.
That is good. That is the contrast in life every day. When you come back home from your job, relax and sit for meditation for a few minutes every day. Nothing stops you from doing that.
Just like we have dental hygiene, meditation is for your mental hygiene. Listen to knowledge regularly. That is why I have made so many talks. For nearly seven years every Wednesday, I used to make some knowledge sheets which are compiled in the book called Intimate Note to the Sincere Seeker. Pick up knowledge sheets from that, or play some knowledge talk and listen to that.
Meditation is more relevant when you are very busy, and when you have a lot of responsibilities to attend to. If you have nothing to do, what is the point of you sitting in meditation? Why would you need energy then? You need energy and intelligence when you need to use it. If you have nothing to do, what is the need for a lot of intelligence?
