Nadi Porutham Basis

Nadi Porutham is a traditional Nakshatra-based compatibility classification used in Vedic astrology. The system divides Nakshatras into different Nadi groups, which are considered when assessing compatibility between two individuals.

The classification provided here consists of three principal Nadi groups: Right/End Nadi (Dakshina Parsva), Middle Nadi (Madhyogha), and Left/Start Nadi (Vama Parsva). An additional Exception (Vilakku) group is also included in the reference.

The Three Principal Nadi Groups

The reference divides the primary Nakshatra classification into three Nadi groups. Each group is also associated with a traditional Varna designation in the supplied table.

Right/End Nadi (Dakshina Parsva) - associated with Kshatriya in the supplied reference
Middle Nadi (Madhyogha) - associated with Brahmana in the supplied reference
Left/Start Nadi (Vama Parsva) - associated with Vaishya in the supplied reference

How to Identify the Nadi

To identify the Nadi associated with a Nakshatra, locate the Nakshatra in the classification table. The corresponding column indicates its Nadi grouping according to the supplied reference.

For example, Ashwini is listed under Right/End Nadi (Dakshina Parsva), while Bharani is listed under Middle Nadi (Madhyogha). Krittika appears under Left/Start Nadi (Vama Parsva) and is also separately listed in the Exception column.

Exception (Vilakku)

The reference includes a separate Exception (Vilakku) column containing Nakshatras that are also marked as duplicates of entries appearing in the principal Nadi groups.

These entries include Swati, Shravana, Krittika, Rohini, Mrigashirsha, Magha, Hasta, Anuradha, Moola and Revati. Because the source itself marks several of these entries as duplicates, they have been retained without attempting to resolve the classification.

Nadi Porutham

In traditional astrology, Nadi Porutham is considered as one of the factors in marriage compatibility analysis. The Nadi associated with the Nakshatra of each individual is identified before applying the relevant traditional rules.

The classification shown above should therefore be treated as the reference table for identifying the Nadi associated with each Nakshatra.

Nadi Porutham is based on the classification of Nakshatras into Nadi groups. The supplied reference identifies three principal groups: Right/End Nadi (Dakshina Parsva), Middle Nadi (Madhyogha), and Left/Start Nadi (Vama Parsva), together with an Exception (Vilakku) category.

Correctly identifying the Nadi of each Janma Nakshatra provides the basic reference point for applying the traditional Nadi Porutham rules.
