Does the power of password work in spiritual world?

Are there secret passwords in the spiritual world? Some religions believe that but they forget that in spirit world there are no words buy feelings that are conveyed and carry meaning. I went to a ceremony of the Chinese Buddhists where they gave five sacred words that must not be spoken loud or written down. They talked about the three treasures and remembering these words was one of them. To be in the third eye was the first treasure. The third eye is called the 'Portal of Heaven' / Gate of birth and death / Way to enlightenment.

Then was the hand gesture. The base of the ring finger is suppose to be the beginning and the base of the littlest finger is the ending of a cycle of 12. One is suppose to hold the base of the ring finger of the right hand with the thumb of the same hand and the base of the littlest finger with the thumb of the left hand, with the left hand gripping all four fingers of the right hand.

The five words were the Third treasure. They suggested that these words should be remembered everyday before dawn as those who don't practice everyday will forget them when they die and need to remember them as they will get stopped at the Gate of heaven and can't proceed if they can't remember the three treasures.

Its very interesting as Gurbani says 'Panch Shabad (Five Words) Tit Ghar Sabhage, Ghar Sabhage Shabad Waje, Kala Jit Ghar Dhariya.'
