The software takes text, even a web page, and analyzes it for the number of times a word appears in the text, then it gives a relative size to the word: larger type means more instances appeared in that text.
It's a powerful visual way of analyzing text, to see what it's all about.
These are all different versions of the same text, as the site allows you to choose color, type, orientation, etc.

Lord Siva is the Supreme Being of the universe, not one of many gods. To Saivites Siva is the supreme being; to Vaishnavites Vishnu is the supreme being. The soul starts with experiencing the world. On one side the soul is pulled by veiling grace toward the world. On the inside the soul is pulled by revealing grace toward God. Resolving karma, maturing in the world, fulfilling dharma, we move toward imperturbability, realization, moksha.
