The 6th house in Vedic astrology is associated with tasks, challenges, enemies, and illnesses. When the Sun is placed in the 6th House for lagna Aquarius, it implies that the native would need to put in additional effort to overcome obstacles and may face troubles related to health and adversaries. Sun being neutral in this sign state shows that its energies may not be exceptionally strong or weak, but it still plays a vital role in shaping up one's destiny.
