What does music from 2,500 years ago sound like? Until recently, no one knew.Tarun Sekar, shares how a simple question "Why do we only see Western instruments , where are our own ancient Indian instruments ?"led him on an obsessive journey to resurrect the Yazh, an ancient Tamil harp lost to history for over two millennia. With no working instrument to study, no recordings to guide him, and only fragments of poetry from Sangam literature, Tarun spent a year piecing together clues from ancient texts. His curiosity refused to let him quit & he succeeded in bringing back a sound unlike any Guitar or Veena, a voice from India's forgotten musical past coming alive again. Tarun proves that small curiosities can unbury centuries of silence. His work challenges us to ask: What melodies & wisdom from our own heritage are we ignoring? Can Entrepreneurship be our way to explore our world & build what matters?

In this powerful TEDx talk, veteran educator David explores how children’s “misbehavior” often hides a single question: Am I safe with you? Drawing on neuroscience and decades of experience, he introduces the CALM method—Center, Affirm, Lead, Meet—as a roadmap for connection instead of control. His message is clear: when adults choose calm over chaos, we don’t just change behavior—we transform lives. If you’d like to contact Dr. David A.
