Brass Meru Shree Yantra is a primitive, rare, and valuable Yantra created by 'Aadi Guru Dattatreya' for the benefit of the common man. "Koorm Prishthiya Meru Shree Yantra" refers to a Shree Yantra mounted on the back of a tortoise and facing upwards. In relation to Lord Kachhap avtar (incarnation of Lord Vishnu), it is also believed that the tortoise lifted the weight of the earth over its back. Sri Yantra is the yantra's king. Its strength and auspiciousness are multiplied when it is placed on the back of the tortoise. It should be kept in the east or northeast direction of your home or office, and it can also be kept in your home or office's Pooja room.
