Sage Vishwamitra used his extraordinary penance powers to create a separate heaven (Swarga) for King Trishanku, who wanted to ascend to heaven in his mortal body. When the gods refused Trishanku entry into their heaven, Vishwamitra created a new celestial realm between earth and the original heaven, known as Trishanku's Swarga. Sagar, HarishChandra, and Bhagirath were other kings but not associated with this specific miracle.
