The lagnesh, or ruling planet, of the 6th house is traditionally considered to be Jupiter. Jupiter is often associated with good fortune, luck, and expansion. It is also considered to be a planet of wisdom and knowledge. Therefore, the 6th house is often linked with these concepts.

The 6th house is also traditionally linked with the element of fire. This is because fire is often seen as a destructive force, which can represent the challenges and obstacles that we face in life. However, fire is also seen as a source of light and heat, which can represent the positive aspects of the 6th house.
