Vishvamitra's Characteristics
As a former king, and one over as vast a realm as he had been, Vishvamitra was known to retain a regal and often haughty bearing. He was known for his high temper and often cursed people in his anger, thereby depleting his yogic powers obtained by much penance. People feared his temper and prayed that their actions might not get misconstrued by the touchy sage.
However, as a former king, Vishvamitra also possessed great compassion for all beings. Having taken pity on Trishanku, he willingly exhausted all the punya he gained from his tapas, to enable him to ascend to the heavens. Following his attainment of the status of brahmarishi, he was known to use the power of his tapas to help anyone who was in need, whatever the cost to himself.
Kaushika's love of Menaka is considered to have been intense and passionate.
