The substances offered to Paduka must not be mixed with other substances; we maintain separate sets of vessels for cooking, vessels for Perumal aradhanam, etc. Similarly, we need to have a separate set of vessels for Paduka aradhanam. Offerings such as flowers, fruits, etc. that were offered to Paduka-s must not be mixed with substances offered to Perumal. Hence if substances such as Kesari, etc. are offered to Paduka-s, they cannot be mixed with offerings for Perumal. Plus, as they’re also mentioned in the tradition that Paduka aradhanam is to be performed in a simple manner. It is said it is enough to perform Paduka aradhanam with simple offerings and special substances such as Kesari are not needed. Performing Paduka aradhanam that conforms to the ordains of tradition is special.
If possible, do include the Paduka-s of the 46th Srimad Azhagiya Singar. Though it is not a must, it is superior to perform all of these with devotion.
It is not appropriate to use the divine bell used for Perumal Tiruvaradhanam for Paduka aradhanam. One must have a separate unconsecrated divine bell for Paduka aradhanam. It is not a must to offer a divine bell to Paduka-s, but doing so is considered special.
Though both Perumal and Paduka teertham-s are sacred, to differentiate them both, we sprinkle Paduka teertham first before partaking and sprinkle Perumal teertham after we partake in it.
Because an Acharya unites us with Perumal, it is said that the Acharya is superior. It does not mean he is superior to Perumal since he is also a servant of Perumal. It is only the Perumal who is the supreme Lord of all and there is no one greater than him. Acharya is considered superior not because he is greater than Perumal, but because he unites us with Perumal. An Acharya is always a servant of Emperuman, hence we must place his Paduka-s at a level lower than that of Perumal.
Tulasi is dedicated solely to Perumal and must not be offered to anyone else. Since it must not come into contact with legs, it is not offered to the Paduka-s. Tulasi is a Nityasuri serving Perumal. We are servants of such Nityasuri-s. So, even if it is one’s Acharyan, Tulasi must not come into contact with his legs.
There is no need to perform thirumanjanam for Paduka-s during the solar eclipse and instead, it can be done after the eclipse.
