Is there any documentary evidence for Shankara's suffering with Bhagandara disease?

[Shri Subrahmanian asked: In the blog it is stated “The same Shankara suffered with blood motions (Bhagandara Roga) and the death of the body took place due to that “. Is there any authoritative documentary evidence for this? Thanks. By, V. Subrahmanian]

Swami Replied: - These points are not important compared to the points of the commentary of the great Shankara, Who is the incarnation of God Shiva. He made some incident like this as a path to leave His divine body. There is also a story that He walked in the Himalayas leaving the disciples in Kedarnath and God Datta appeared before Him embracing Shankara saying “My brother Shankara! You have done a lot of My work” and Shankara merged in God Datta. Shankara is the omnipotent God Shiva, Who can do anything. In such a case, it is not necessary that He has done something this way or that way. When both ways can be done, you can take any way because a way not done by omnipotent God can also be treated as if it is done. In the case of a less potent human being, such debate is fruitful because a human being may be able to do something one way only and not in any another way. There is also another version that He climbed the 100 steps of the Kailasa mountain and composed 100 slokas on Goddess Parvati, Who appeared to Him inviting Him back home. I consider all these three incidents to have happened. Abhinava Gupta, a Shakteya, defeated by Shankara in arguments did some black magic due to which the Bhagandara illness attacked Shankara. The fact here is that Shankara wanted to leave the body and hence, that black magic was accepted by Shankara as a pretext. Then, He walked in the Himalayas. God Datta appeared and appreciated Him on the way. Finally, He climbed the Kailasa mountain. By this, all the three versions are satisfied and since no version is impossible in the case of Shankara, we can accept all these three versions. By these versions, the commentary and philosophy of Shankara is not going to be affected in any way, which is the most important subject for us.
