Stairway to heaven• In psychological terms, the term Stairway to Heaven is a form of collection of beliefs that the

mind perceives as to what each part of the stairs represents. For example, if a person is at the top of the stairs, it would represent that they had done good with their life and have achieved their goals and dreams come true. If the person is seen at the bottom of the stairs, it is believed to represent that the person has dropped in life fulfillment and are at their lowest point.

One of the fascinating things about Tianmen National Park is that it is located in Zhangjiajie City, China.

The stairs itself lead gradually up to a very astonishing natural formation not usually seen in many areas. Within that rock formation is a famous cave that many visit while at the park. The cave is named Tianmen Cave and in 1999 became one of most popular sites for many attractions. In that year a famous acrobatic show used three planes to fly through the area which must have been something awesome to see for yourself. The cave itself is supposedly only some really big open area but the people claim it to be an actual cave. Though the cave is also very famous for it is one of only a select few that reside at such a high attitude.
