The "Guru Meditation" thing is just a silly name for the particular computer error you're getting. When you get an error that says 503, it usually means there is something wrong with the server where the website is hosted - for example, it may be overloaded or may be down for maintenance. I'd say just try that page again in a bit, and if it keeps happening, contact support!
