In Vedic astrology, opposition (180° aspect) is often considered challenging.
Every planet naturally aspects the 7th house from its position, creating tension between self and other, origin and destination. But what happens when the lord of a house itself is placed in the 7th from its own house? This placement can bring both loss and transformation, but also balance and unexpected gains depending on dignity, aspects, and strength.
The fundamental tension in all these placements is between the House Lord's
need to protect its sign (the house it rules) and the force of the 7th aspect, which is inherently challenging, confrontational, and consumptive.
