Sandhya, also known as the twilight period, is considered an important time for spiritual practices in Hinduism. It is believed that the energy of the universe is heightened during this time, making it a powerful time for meditation, prayer, and other spiritual practices. Sandhya is traditionally marked by the recitation of the Gayatri Mantra, a sacred hymn that is believed to offer protection and blessings to the devotee. By observing Sandhya, Hindus seek to deepen their spiritual connection with the divine and to cultivate inner peace and harmony.
