KP Astrology considered western aspects (పాశ్చాత్య దృష్టులు). Western Aspects are relative to the angular relationships between two planets. So the Western Aspects run both ways, or in both directions. It is the angular degree of separation on either side that actually determines the aspect.
Western Aspects helps to understand the relation between the planets. Any connection between dasha lord and bukthi lord (connections like aspects, star, sub, conjunction) helpful in judging the dasha-bukthi, even useful in birth time rectification.
