Usually during yoga meditation, people tend to get totally lost in their thoughts. For many people, yoga meditation allows their mind an escape from the worries of life into a world that is full of peace and happiness. And perhaps this is why yoga is believed to have mood improving and relaxing effects on the mind. People also tend to experience time lapses.
Usually, a lot of time would pass and you would feel like only 5 to 10 minutes have passed. Apart from that, during yoga meditation, the body feels totally relaxed with a shallow level of breathing.
