HOW high is CLOUD 9???

Very often people say they are on cloud 9 indicating a feeling of utmost happines or achievement. What has this cloud named as "9" got to do with it? Why not any other cloud? Well the myth goes this way......In Dante's Paradise, the 9th level of heaven is closest to the Divine Presence, which itself dwells at the 10th and highest heaven. This notion may have enhanced the popularity of the expression on cloud nine......there are another set of people who have other reasoning......The US Weather Bureau arranges the cloud formations in a numerical sequence, with 9 levels of clouds. Types of clouds are numbered according to the altitudes they attain, with nine being the highest number a cloud can be assigned. So if someone is on cloud nine, that person is floating well above worldly cares. :) Another account evokes the mystical quality of the number nine. Nine is a trinity of trinities -- three threes equal nine -- and as such is considered the perfect number......but my numerology has got different numbers for me. I believe the second one suits us all where in each one of us believe we are better than every single human being on the Earth.
