I'm really happy you were able to achieve peace after your meditation. I recommend really focusing on your breathing during meditation, and not breathing Thoracically, but breathe through the diaphragm. It's difficult to explain online, but you'll know you're doing it properly when you take deep breaths and your shoulders and chest stay level and unmoving, except the diaphragm contracts and expands, giving the illusion of inflation of the stomach region. I have found that I enter very deep trances during my meditation, even if I only do it for 5-10 minutes. My body becomes like a stone; my muscles completely relaxed but very rigid and not moving. Just a very enlightening tip I received from an incredibly knowledgeable person who learned from several different Masters. It really helped me enter into a deeper state of relaxation, and I hope you're able to put it to use as well. Cheers.
