How deep do you want to go? I have read that the entire spacetime continuum can be summed up as the first symbol in the Mool Mantar. I'm not deep enough to know whether it is true or not. If it is true, it simplifies things immensely.
Actually you didn't say that..
People do care about external appearances. Even those amongst us who are the most liberal and non-discriminatory care..
I'm sure we all believe and strive for equality and non-judgemental eyes but we don't.. To have done that it would mean we have lost our ego.. And I'm pretty sure that whilst we all strive for that none of us have achieved it..
