Foreign money to indian bank accounts

Hello,

My question is this:

I am an Indian individual holding an account with an Indian Bank.

Now I will be receiving money from foreign sources outside India. This money is to conduct charitable programs or sometimes I get paid for content writing, freelance journalism etc.

What are the issues with the Income Tax Department?

Am I answerable to anyone about these amounts?

Is there a limit on the amount of money that I can receive?

Will this be looked upon as a donation made to me and taxable in my hands?

Would be grateful for clarifications on this topic.

Thanks,

Aneesh
