We all—whether Hindu, Muslim, Sikh, or from any other community—should use our real surname or gotra instead of common caste- or religion-related surnames like Kumar or Singh.

According to science and many religions, diverse DNA is essential for healthier and safer children. A surname acts like a code that indicates different DNA.If you want to use prefixes like Chaudhary, Thakur, Sri, Khalsa or Sardar before your name, you can, but you should always include your original surname.If someone chooses to live a single life or become a saint or spiritual person, they may use titles like Singh or Khalsa. However, we must use our original surnames without hesitation or fear of defamation. Only people from Sikh or Islamic missionary backgrounds tend to mock surnames, but in reality, even they consider surnames when arranging marriages.In Sikh communities and among those using surnames like Saini, Jain, or Rajput, boys and girls often feel attracted to others from the same caste. However, after forming a deep connection, they may later realize that they share the same surname, which can cause emotional distress. Some people even try to convince their partner by saying, “We are all children of the same father and mother,” but this is incorrect. Our spiritual father is one, not our physical father.Just as different breeds of dogs and horses have unique qualities, human beings also have distinct appearances and DNA types. This can be scientifically proven in laboratories
