Translation: I will try. (English is not even my second language). You may attach an eagle's wings to a dove, but ambition to fly high in the sky must be present in blood. It can not be attached.
I don't know what is an English word for गगनभरारी. I will explain my context which might make sense. Context I use this quote usually at my work place. Some people expect me to motivate everyone (being CEO of company). While I like to push people and bring best out of my team, I am aware that I cannot sharpen anybody's skills or career unless they are ambitious about it themselves. Another context I use this is to stop elder people pushing their son to get into family business/profession.
I try to argue that if they don't have dreams like yours, they won't excel is same business/profession as you did! A slightly different but related quote from English could be: Give a man a fish and you feed him for a day.
