Money in bank account for EC

Hi,

If after the HSMP is approved, for the purpose of immigration, what amount should be there atleast for a person in out bank account (in Indian Currency)?

Also, what are the various sources from which the amount can be deposited in our account.......I cannot take loans from bank now as I have already taken loans for other purpose.......So, I was bit worried, can my relative put money in my account for time being to show good balance. Please suggest. Thanks.
