Verse 17.21
यत्तु प्रत्युपकारार्थं फलमुद्दिश्य वा पुनः । दीयते च परिक्लिष्टं तद्दानं राजसं स्मृतम् ॥ १७.२१ ॥
किंतु जो दान क्लेश पूर्वक तथा प्रत्युपकार के  प्रयोजन से अथवा फल को दृष्टि में रख कर फिर दिया जाता है, वह दान राजस कहा गया है|
However Arjuna, when the gift is given with the expectation of receiving something in return, when it is also given for the sake of receiving future rewards or when the gift is given unwillingly from one person to another, this gift is considered impure and presented by a person of the Rajas nature.
