Shrimad Bhagwat Mahapuran, Pancham Skandha , Chapter 16
While describing the character of Mahārāja Priyavrata and his descendants, Śukadeva Gosvāmī also described Meru Mountain and the planetary system known as Bhū-maṇḍala. Bhū-maṇḍala is like a lotus flower, and its seven islands are compared to the whorl of the lotus. The place known as Jambūdvīpa is in the middle of that whorl. In Jambūdvīpa there is a mountain known as Sumeru, which is made of solid gold. The southern side of the land is known as Ilāvṛta-varṣa. To the south of Sumeru are the mountains Kailāsa and Karavīra.
In the same chapter it also says:
When all those solid fruits fall from such a height, they break, and the sweet, fragrant juice within them flows out and becomes increasingly more fragrant as it mixes with other scents. That juice cascades from the mountain in waterfalls and becomes a river called Aruṇodā, which flows pleasantly through the eastern side of Ilāvṛta.
Kailāsa is to the south of Sumeru parvat, Aruṇodā is in the eastern side and In my question How can Jamuna river be in India when shastras say otherwise?, I have shown that Aruṇodā (also known as Arun river) is in Nepal. If this is the case, Which one is the real Kailāsa? The one in Tibet or the one that touches Aruṇ river in eastern Nepal?

Note: I do not wish to offend anyone regarding my question. Our current thirthas are as holy regardless of their authenticity and I respect their location. Being a Hindu, I would never disrespect any thirth just because they do not match with shastras. Many thirthas have changed locations and this is why I try to find their original location. Sorry if I have offended anybody.
