If you read the sakhi about Gurudwara Nankana Sahib and how it got freed from the evil mahant, you will know what I mean. Most of our natural instict would be to fight in those conditions. But look at those Singhs that gave their lives but did not fight back. It was their scarfice that brought the whole panth to arms and made the mahant run away, so the Gurudwara Sahib could once again be under the khalsa rule.
There is no cryptic message. and you don't know if you have a good connection, only guru ji knows. Just be honest and even if it sounds silly, tell Guru Ji exactly how you feel about what happened in the langar and then ask for advice on what to do. After ardas, take hukamnama. If you can't understand the hukamnama post it on sikhsangat and I am sure many people are ready to help you understand the hukam and follow it.
