Despite many entreaties, young Seshadri Swamigal was far too detached and had completely renounced any attachment to the worldly life forcing his relatives to let him pursue a life of a renunciate, Sanyasi and a mendicant. After a gap of 2–3 months, where his whereabouts were never clearly known, likely because he never spent much time in any one place, he finally arrived at Thindivanam very close to Tiruvannamalai. By then, he had taken a vow of silence, and was known as "Mouna Swamigal" (the Saint in Eternal Silence (Mounam)). A devotee by name T.K. Kanniyar requested the priest of the famed Sri Thinthirineeswarar temple to open the temple Yangyasalai for Swamigal to meditate. Swamigal requested that the room typically used for performing Homas, fire rituals, be locked from outside and opened after 4 months. Yet, in a spate of worry about Swamigal's health, Sri Kuppuswamy priest opened the same on the 5th day only to find Swamigal in deep meditation. On hearing of the priest's apprehension, Seshadri Swamigal left Thindivanam immediately. Passing through Maarchettikulam, he reached Aiyyanthoppu before his traces were again lost until he resurfaced a few months later in the famed Pandava Caves of ThoosiMamadur village south of Kanchipuram wherein, on hearing of his presence, crowds gathered, which crowds also included Swamigal's biological younger brother, Sri Narasimha Josiar. But before he could meet his older brother, Swamigal had left ThoosiMamadur to reach North Arcot where he spent some time in Muthukumaraswamy temple and Brahmeswaraswamy temple in Fort Street, North Arcot.
