In India, it is an exceptional salary to begin with and not may professionals are that fortunate enough to start their career with a package like this.
Having said that, the below points would be worth analyzing:
1) At this point of time, is it fine to be content with this salary and concentrate on building a solid career foundation, or search for a job with a better pay owing to some unavoidable financial responsibilities?
2) Are you accepting the job offer just for package sake or you are actually excited and serious about the opportunity?
3) Every package comes with expectations. Are you absolutely confident and sure of yourself that you would be able to exceed, or atleast meet, those expectations, in return for a hefty paycheck?
If you are able to find appropriate answers to these questions, I am sure you would be able to make an informed decision about your career.
It's always good and brave to dream big, but at the same time you should be aware of your strengths and weaknesses as well.
Hope this makes sense to you. Cheers and good luck.. :)
