Planets become weak and debilitated and lose the power to provide auspicious results in certain signs.
Sun is the weakest in Libra, Moon in Scorpio, Mars in Cancer, Mercury in Pisces, Jupiter in Capricorn, Venus in Virgo and Saturn in Aries.
Debilitated planets represent some kind of a curse. How do we get rid of that? The power and magic lie in the worship of Jyotirlingas.
I learned this from Pandit Sanjay Rath who is my Jyotish Guru
A Jyotirlinga or Jyotirlingam is a devotional representation of the Supreme God Shiva. “Jyoti” means ‘radiance’ and lingam means the ‘Image or Sign’ of Shiva; Jyotir Lingam thus means the Radiant Sign of The Almighty Shiva. There are twelve traditional Jyotirlinga shrines in India. And each Jyotirlinga is connected to a zodiac sign.
So all you need to do is, find the sign where the debilitated planet in your chart gets exalted and then find the Jyotirlinga connected to that sign.
For example, Venus gets debilitated in Virgo and exalts in Pisces. So if Venus is debilitated in your chart, you need to pray to the Tryambakeshwar Jyotirlinga to get rid of the curse associated with Venus.
Here are the signs where every planet is exalted and debilitated.
