Fabulous Temple Escape

You are a big businessman and you have been very working day in and day out. Now you are too weary and you want to go out on a vacation to relax. Luckily you have a very capable brother who you appoint to look after the business in your absence. You visit an ancient temple in the city that you go to for your vacation. You go around the temple appreciating the amazing architectural work that you see there but after some time when you decide to leave the temple you find that the main gate is locked. You should find another way to get out of the temple or find a key or code to open the main gate.
