Why putting mootai in tirupathi?

Mootai, or the practice of offering hair, is a significant ritual at Tirupati's Venkateswara Temple. Devotees believe that shaving their heads symbolizes humility and surrender to God, expressing gratitude for blessings received. This act of devotion is rooted in the temple's rich tradition, where hair offerings are considered a form of sacrifice and a way to seek divine grace. The collected hair is often donated or sold, with proceeds supporting various charitable activities.
