You do not have to go through this. You may change your name legally for any reason as long as you are not trying to defraud anyone if you live in the US or a common law country. Your name is someone that you choose to be known by.
Generally you just need to go to a judge and get a court order of your new desired legal name, and prove that you aren't trying to evade taxes or defraud anyone. Then you can bring that paperwork to the proper people.
Look up the process in your new state and get your documents reissued.
EDIT: if you still want to keep Mohandas, maybe try keeping it as a second name, or part of your first name. Like you can be "Schuyler Mohandas" as your first name. Having two first names is common in some areas, such as the American South.
