Arjuna once asked Lord Krishna why Yudhishthir is called Dharmaraj and Karna Daanveer, even though they never denied alms to anyone. Krishna says: wait a minute and I will let you know. After a month, it was raining heavily across kingdom, when Krishna and Arjuna, disguised as brahmins, went to Yudhishthir for the first time saying that we are making Yajna we need 100 kg of sandalwood. Yudhishthir immediately sends his servants across the kingdom and then refuses to say that it is difficult to find dry sandalwood anywhere.
