Yantras are geometric diagrams or symbols used in Hinduism and other spiritual traditions for various purposes, including meditation, worship, and attracting positive energies. They are considered sacred and powerful tools for focusing the mind, invoking specific energies, and connecting with higher consciousness.

Yantras are typically composed of intricate geometric patterns, often in the form of a mandala, and may include specific symbols, mantras, or deity representations. They are usually engraved or drawn on metals, such as copper or silver, and can also be made using other materials like paper or wood.

When using a Yantra, it is important to understand its symbolism and purpose. Yantras are typically energized and activated through a process called Pranapratishta, which involves invoking the deity associated with the Yantra and infusing it with sacred mantras and rituals.

Yantras can be used for meditation by focusing on the geometric patterns and symbols, chanting mantras, and invoking the associated energies. They can also be placed in homes, temples, or personal spaces as a source of positive vibrations and spiritual presence.
