Vedic rituals like Brahma yagna and Tiruaradhanam are classified as Anushtanam.
Acaram grants the qualification to render Anushtanam.
Notes:
Anushtanam should be performed after purification.
One should bathe before proceeding to perform any ritual. One should perform sandhyavandanam without coming into contact with others and hands must be kept clean to perform any ritual. These are termed Acarams.
Acaram provides the essential cleanliness for performing Anushtanam.
Acaram combined with Anushtanam is considered special.
There is no benefit if one simply follows Acaram without performing Anushtanam asserts Sri Bashyakarar.
