Aaj Sooraj lagan ka chalana hai, sabko raasta dikhana hai. Kya hua jo khud jal raha hoon, parivar ko arsh pe chamkana hai.
Today the Sun of the Ascendant has to walk, has to show the path to everyone. What does it matter if I am burning myself, I have to make my family shine in the sky.
The Sun (Surya) in the 1st house (Lagan) makes a person the absolute leader and provider of their family.
Dr. Rishi Rohit Sharma beautifully captures the emotional sacrifice of this placement. The Sun gives light to the world, but it has to burn itself to do so. Similarly, a person with Sun in the 1st house takes on the entire burden of their family.
They will work themselves to the bone, endure massive stress, and "burn" their own desires ("khud jal raha hoon") just to ensure that their family reaches the heights of success and respect ("parivar ko arsh pe chamkana hai"). They are the torchbearers of their lineage.
