Different spellings for Sanskrit words..
I'm looking to get the word "gratitude" tattooed as a regular reminder of my many blessings. I looked it up online and there appears to be almost up to 5 different spellings purported to mean 'gratitude.' I know that Sanskrit is spelled phonetically, so I was wondering if anyone knew whether precise spelling really matters and what the difference is between the different spellings, if anything.
Can someone also tell me the most appropriate spelling for it, given the context I'm looking to use it? Thank you!
