Khud jalega jo doosron ko tu taap na dega, gar huya bura yahan pe toh saath baap na dega.
You will burn yourself if you do not give heat to others; if it becomes bad here, even the father will not support you.
Following the previous post, Dr. Sharma reveals the dark side of Sun in the 1st house.
If the Sun is afflicted or weak here, the person's sacrifice goes completely unappreciated. They will burn themselves out trying to help their family, but they will not be able to provide enough "heat" or success ("taap na dega").
The tragedy is that when this person eventually fails or faces a crisis, the very family they sacrificed everything for will abandon them. Dr. Sharma warns that in extreme cases, even their own father will refuse to support them ("saath baap na dega").
