Currently PayPal doesn't allow Indian users to receive funds or receive donation. It will say "Currently PayPal does not allow payments to India".
This is how you need to donate-
1. Login to your PayPal account.
2. Go to 'Send Payment'
3. Pay for either services or Goods. Personal payment option won't work.
4. Enter my email id "email@example.com"
5. Make the payment of the desired amount of donation you want to send.
For INDIAN users-
You can follow same procedure or use NEFT service to make payment.
