When you go out to ask for bhiksha, it should be done without wearing a shirt/t-shirt. You should not look at the amount others are putting in your hundi. You can keep your head down while receiving bhiksha. It is best if you get bhiksha from unknown people. If you are not able to go for Bhiksha in your locality, please ask your family members to offer bhiksha. You can collect the offerings in the bhiksha hundi and bring it with you to Dhyanalinga on your next visit.
