Yantra by TreeFrog

“ 'Yan' means to control, curb or influence and 'Tra' means a tool. Yantra is a tool or diagram illustrating sacred geometrical arrangement in a symmetrical design which emits cosmic positive energies, curb negative energies and help individuals upraise spiritually. Usage of Yantras has been practiced since 3300 B.C as they were also found from excavation of Harappa civilization. Assuring benefits of Yantra has led to building of temples in the shapes of Yantra as mostly seen in Southern India.” https://timesofindia.indiatimes.com/astrology/others/what-are-yantras-how-does-it-help/articleshow/79407529.cms
