Some people confuse labyrinths with mazes, but it's not a maze. It is more of a meditation that is in walking form. Let me explain. The labyrinth has a pathway that you walk in order to reach the center but it goes round and round, back and forth, until you reach the center. The key is to take slow steps and just walk towards the center; taking your time and following your breath.
Gurdjieff has prepared a group of dancers. The dancers created such a meditative energy, such a great wave of energy, that those who had come just to see the dance, suddenly forgot the dance completely. Something else was there by the side, a door opened through it.. (commentaries by osho)
Often lots of people's third eye are not open because they are blocked. The third eye is a sixth chakra but connected to the first, second and third chakra's and blockages in this lower chakra's will also cause a blockage in the sixth. Oftentimes, the cause of blockages are fear and disbelief, though Tibetans and Indian yogis believe third eye is blocked for past life karma . Some people refuse to believe that they are blessed with a sixth sense while others are anxious of the images they might see once they have opened theirs.
