One has to perform Tiruvaradhanam to the best of one’s ability in maintaining the orthodoxy. If well water is not available, arrange for water from Direct Borewell; if this is not possible, make sure the water offered is pure.
Notes:
Those who live in apartments should strive to offer pure water for Tiruvaradhanam; one can take some water from a nearby well for Tiruvaradhanam; or shift to an apartment that has a well, or arrange for a bore in your apartment where the water can be pumped from the bore well directly. These reflect our efforts in offering the purest to Perumal; where there is a will there is a way. One has to perform Tiruvaradhanam without fail, it is fair to offer pure water as well.
