Puja is a Hindu ritual of prayer and worship. It is a way to connect with the divine and to seek blessings. One of the most important aspects of puja is the lighting of a diya, or lamp. Diyas are made from a variety of materials, including clay, metal, and glass. Brass diyas are a popular choice for puja because they are durable, long-lasting, and easy to clean. They are also a beautiful way to add a touch of tradition to your puja space. Brass diyas are made by melting and casting brass into molds. The molds can be made from a variety of materials, including clay, metal, and wood. Once the diyas are cast, they are cleaned and polished. Some diyas are then decorated with images of gods and goddesses, or with other symbols of faith.
