Ch2 : The Kanchi Mutt.

let's see how Our Jagadhguru entered the Kanchi Mutt, Kanchipuram:

In the first week of February 1907, the Kanchi Kamakoti Math had informed Subramanya Sastrigal that Swaminathan's first cousin (son of his mother's sister) was to be installed as the 67th Peetathipathi. The presiding Acharya was then suffering from smallpox and had the premonition that he might not live long. He had, therefore, administered upadesa to his disciple Lakshminathan before he died. Sastrigal being away in Trichy on duty arranged for the departure of Swaminathan with his mother to Kanchipuram. The boy and his mother started for Kalavai (where Lakshminathan was camping) to console his aunt who, while also being a widow, had just given up her only son to be an ascetic. They traveled by train to Kanchipuram and halted at the Sankara Math. By then, Lakshminathan had fallen ill.

The 67th Acharya also died, after reigning for a brief seven days as the head of the Mutt. Swaminathan was immediately installed as the 68th head of the Kanchi Kamakoti Peetam on February 13, 1907, the second day of the Tamil month of Masi, Prabhava year. He was given Sanyasa Asramam at the early age of 13 and was named Chandrasekharendra Saraswati. On May 9, 1907 his "Pattabishekam" as the 68th Peetathipathi of Kanchi Kamakoti Peetam was performed at the Kumbakonam Math. Devotees including Shivaji Maharaja of Thanjavur, government officials and pundits participated in the event.
