Legend
The sacred city of Kashi has had a number of Lings built there by famous Rishis, according to Kashi Khand, Chapter 18. (Sages). It is important to note that the Sages have achieved heavenly abilities as a result of their fervent petitions to the Lords.
Sage Angeeras built a Shiv Ling known as Angeerayeshwar in the gardens of Harikes. Worshiping this Ling would let devotees attain Tejas (radiant energy), which will allow them to enter paradise after death.
