One must render services that please one’s Acharya`s divine heart. One must obey their ordains. This will please them.
It is not a must that only when one renders physical services directly in front of Acharyan can one please him. Shrimad Azhagiyashingar while conducting samashrayanam would have instructed one to chant mantras, perform daily Tiruvaradhanam, etc. He will be pleased when one follows their ordains diligently. He will be pleased when we perform the prescribed austerities without fail.
