Ah, someone spotted it! Its quite a common typo! But i have already tried the rest of the ext's unfortunately they have all been regged! Wordtracker says 261 per day for karmasutra and 4854 per day for karma sutra! Although O/t doesnt reg it at all but still shows the correct spelling numbers??? Maybe its confused also!
the problem results from people's ignorance of Sanskrit and related dialects. karma, in simplistic terms, refers to a sort of moral cause-and-effect that has been popularized in New Age books, and pop culture. Kama literally means pleasure, with the implication being carnal pleasure.
