When we talk about Tibetan Buddhism, Tibet monks' sand art is one of the ancient traditions in the artistic aspect.
In Tibetan culture, it's believed when young children see the Tibetan Buddhist sand mandala, they get positive energy. Therefore, resulting in a peaceful and harmonious behavior when they grow older.
It is said that as long as you visualize the mandala, you can obtain vipassana or inner peace. If you can see the mandala, you will establish a deep relationship with the deity. The mandala can also purify the polluted environment and bring prosperity to the world.
If we go by the beliefs of Tibetan Buddhists, each sand mandala has its own outer, inner, as well as secret meaning associated with it.
On the outer aspect, it's the signs of a divine form, while on the inner point, it's a way for a being to transform into an enlightened one. As for the secret level, the Tibetan sand mandala signifies an ideal balance of different energies of the body.
All these different aspects join together to purify the heart of a human being and perform healing at different levels too.
