Jai Shri Krishna,
Monica ben, the short answer will be to apologise to the vaishnav or vaishnavs, and ask for forgiveness. Also to try and not repeat the same mistake, in future do things that might please that vaishnavs or other vaishnavs in general.
In the varta of Ramanand Pandit, while Mahaprabuji was birajmaan at his place, in night he said to his wife
"Gobar jaldi sametlo, vaishnav kal ley na jaye" "take the gobar away quickly, as when vaishnavs come they will take some"
hearing this Mahaprabhuji was very upset and right away left Ramanand Pandits house and also the gaam. Many other vaishnavs requested Mahaprabhuji to come and stay and their place, but Shri Mahaprabhuji refused everyones offer and went to a far away village with close sevaks.
The reason being, that if Mahaprabuji was in same village, then Ramanand Pandit would come and apologize and Mahaprabuji would pardon him.
His main sin was that he had offended all vaishnavs, as he did use anyones name. which included vraj bhakts and vaishnavs all over. thus Mahaprabhuji was severe and told I tyaag Ramanand pandit.
Later Mahaprabuji was in Adel, and mean time Ramanand pandit, lost all his achaar vichaar. But when ever he would eat something, he would offer it to Shri Goverdhan Nathji in his mind. One day he saw jalebi and offered it to ShriNathji, who accepted his offering. This was seen by Shri Mahaprabuji, that Shriji Bawa accepted Jalebi offered by Ramanand Pandit. Shri Mahaprabhuji asked Shriji Bawa that
I have done tyaag of Ramanand Pandit, then how come you are accepting offering from him. Shriji bawa said I am doing this because I have promised you that which ever jeev takes Bhram Samband I will never leave him or forget him.
Later some vaishnavs were discussing this prasang with Shri Mahaprabuji and Aapshree mentioned that I will accept Ramanand pandit after few janams, if he never again does vaishnav apradh.
Later Ramanand pandit came to know that Shriji bawa was accepting his offering and that Mahaprabuji said that he will accpet him again, if he does not do vaishnav apradh. This news really pleased Ramanand Pandit.
Bhavprakash: one should be very careful to avoid vaishnav apradh, as Mahaprabuji or Shri Thakorji take it very seriously. But Shri Mahaprabhuji had only done Bahirang Tyaag (for the outside world), to set an example for all vaishnavs in future to be carefull. But Mahaprabuji had not tyaag from his mann (mind), as otherwise Shriji bawa would have never taken anything from that vaishnav otherwise.
Also if Shrijibawa accepted jabeli offered that were made in restaurant, that there is no doubt that samagri prepared with bhaav and offered to Shri Thakorji is not accepted.
This is shorter version of the varta, and please pardon me for any mistakes or not being able to narrate it correctly.

Jai Shree Krishna
