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.

The blessings of Lord Murugan awaken wisdom which resides in his chakra. "Pray to Lord Murugan to unravel the great mysteries of the universe." When we get emotional we lose touch with our wisdom. Murugan inspires penance to soften karmas and purify the mind, chitta-shuddhi. If you do kavadi in the right spirit, to get the full blessing, have in mind specific misdeeds, apologize to the deity, learn from it, promise to do your best. Visions are still happening. Feeling the energy of the deity is stronger during festivals such as Skanda Shashti.
