Partaking Paduka theertham is equivalent to partaking Pancha-kavyam. We take Pancha-kavyam as an atonement for eating foods that are not prescribed. Sripada titham is also similar to Paduka tirtham for atoning. As there is a shloka for Pancha-kavyam, similarly there is a shloka to obtain Paduka theertham for atonement. One has to do sankalpam and accept Sripada tirtham as an atonement for the misdemeanors. One thereby gets purified. Elders have this in practice. One has to obtain the shloka as an upadesam from elders to accept Sripada theertham.
