Bhrigu Nandi Nadi (BNN) is a Nadi-based astrological approach in which planetary relationships, signs, directional movement and combinations are studied to understand how events and life themes unfold. BNN places strong emphasis on the interaction of planets. Instead of viewing each planet in isolation, the astrologer follows the chain of planetary connections and interprets the story formed by those relationships.

The planets are examined through their placements, sign relationships, conjunctions and links with other planets. The astrologer studies how one planetary influence connects with another and how those combinations relate to areas such as profession, relationships, finance, property or major life changes. This makes BNN particularly useful as a complementary predictive and interpretative system when a deeper planetary narrative is required.
