Check out this 20 minute video about the Overview Effect which describes the shift in life perspective that astronauts experience upon seeing Earth from space. In fact, one astronaut had academics research his experience to help him identify this feeling. Their answer, after scouring ancient texts, was samadhi, which is the yogic state of bliss.
This film brought tears to my eyes and I hope it moves you as well. If you don't have time to fly to space this week to experience the Overview Effect, then come join me for a yoga class for a more down-to-earth, but no less elevated, experience.
