What does the Skanda Purana say about Asthi Visarjan in Varanasi?

The Skanda Purana’s Kashi Khand declares Varanasi the supreme city in all three worlds because it was manifested by Lord Shiva as his eternal abode. Those who die in Kashi receive the Taraka Mantra from Lord Shiva and attain moksha. The Ganga at Kashi is uniquely potent because all sacred Tirthas converge in her waters on auspicious days, making Asthi Visarjan there spiritually unparalleled.
