piLLai lOkAchAryar, following in the foot steps of our pUrvAchAryas, out of his causeless mercy, blessed us with a divine grantham named “thathva thrayam (tattva trayam)”. The subject matter of this grantham involves in-depth analysis of the three entities – chith (soul), achith (matter) and Iswara (God). This grantham is called as kutti bhAshyam (mini srI bhAshyam) where the essence of sanAthana dharmam is explained. maNavALa mAmunigaL mercifully wrote a detailed vyAkyAnam (commentary) for this grantham which adds even more value to this grantham.
