Vallalar established a number of institutions that survive today. In 1865 he established a poor feeding center. On the inaugural day he lit the fire of the stone stove, with a declaration that the fire be ever alive and the needy shall be fed forever. Around 1870 he established the Sathaya Gyana Sabai, hall of True Wisdom Forum. This place is not a temple. An oil lamp is kept perpetually burning. There are seven cotton fabric screens, representing the seven factors that prevent a soul from realizing its true nature. The entire complex is bound by a chain with 21,600 links, said to represent 21,600 inhalations by a normal human being.
He called his followers on January 30, 1874 and gave them his final discourse. Later he entered his room. His followers later found the room empty.
