In Vedic astrology, Ketu placed in the Jyeshtha nakshatra can have a strong influence on an individual's life. This placement can bring about some unique challenges as well as significant astrological predictions. The Jyeshtha nakshatra is ruled by Indra and signifies power, authority, and seniority. At the same time, Ketu represents spirituality and transformation. Together, these two energies can create a powerful dynamic that can lead to both positive and negative astrological outcomes.
