Hi. After going through some YouTube videos I am not sure about the right metal for my kada. Lal kitab remedies say I should wear steel kada because Rahu is in the 11th house. Copper can also be worn because sun is in the 9th house. Just like some gemstones shouldn’t be worn together, is there such a rule for kada metals also? For eg Steel and Copper cannot be worn because Shani and Surya are enemies. Please share your thoughts.
