A Garuda (eagle) is Lord Vishnu’s vehicle. Tradition states that the presence of a garuda will keep snakes at bay. And precisely because of this, a Garuda yantra is believed to remove any Sarpa (snake) doshas related to the plot.
In addition to this the presence of Lord Vishnu can also be felt in such households. This yantra will keep away profligacy, illnesses and quarrels in the family. Any doshas resulting from the wood used for construction will also be rectified by this yantra. This yantra should first be placed remembering Lord Vishnu.
