Jupiter (Guru) is the planet of religion, faith, and divine connection. The 10th house is the house of Karma, career, and Saturn's strict reality.
When Jupiter sits in the 10th house, it often goes through a phase of extreme disillusionment. Dr. Rishi Rohit Sharma explains that when this person faces severe hardships or career failures, they don't just get angry at the world ("deen duniya se mooh mod leta hai")βthey get angry at the Divine.
In their frustration, they may temporarily become atheists, breaking their relationship with God ("Rab se bhi rishta tod leta hai") and refusing to pray. This is a dangerous phase, as losing faith only multiplies their struggles.
