Tradition plays an important role in teaching younger generations about cultural heritage. As so, everything must evolve. However, even in evolution, We should pay the highest respect to our culture by maintaining the foundation that said culture’s traditional customs are built on. Doing so will maintain continuity between generations. And will also Help The next generation develop a fonder respect, and a deeper understanding of said culture.
Traditions aren't about whether they are useful or not, they are about respecting our history, and maintaining our foundations.
