By the grace of Acarya, adiyen has performed prappati. Those who performed prapatti should not commit Bhagavata Apacaram (offending other devotees). Have the scriptures specifically pinpointed what is a Bhagavata apacaram and who are Bhagavatas as per our Sampradayam? Are they only devotees of Vishnu or those who worship all Gods including Perumal?

Those who are devoted to Bhagavan are known as Bhagavatas. Those who have undergone Samasrayanam, Bharanyasam, and those who apply thirumankappu on their forehead are all bhagavatas. In general, all are devotees of Bhagavan, and we should not commit any offence against them termed as Bhagavata Apacaram.
We must not scrutinize about the traits of any bhagavata whether they are distinguished or not. It is crucial that we do not commit any offence against them.
