Padhigam — The Decad as Unit of Sacred Song
Padhigam ('a group of ten', cognate with patti = group) is the fundamental compositional and organizational unit of the Divya Prabandham — the 4,000 hymns of the twelve Āzhvārs. A padhigam consists of ten consecutive pāsurams (pāṭṭu = songs) composed as a unified group addressing a single deity, shrine, divine quality, or state of devotional experience.
The exact verse-count and closing structure vary by prabandham. In Tiruvāymozhi and several other works, a thematic unit normally has ten principal pāsurams followed by an eleventh signature or phalaśruti verse in which the Āzhvār identifies the composition and states its fruit. A taniyan, however, is a later prefatory verse recited before a prabandham; it is not the tenth verse of the Āzhvār’s padhigam. The terms “tenth verse,” “eleventh verse,” phalaśruti, and taniyan should therefore not be treated as interchangeable.
In the Tiruvāimoḷi — the greatest of all prabandham texts, composed by Nammāzhvār — there are 100 padhigams, organized into ten paththus (centuries of 100 pāsurams each). Each padhigam of the Tiruvāimoḷi has been given its own name by the tradition, reflecting its dominant theme, mood (rasa), or the state of the Āzhvār's devotion.
The padhigam structure serves multiple purposes: it creates natural units for memorization and recitation, provides rhythmic variation (each padhigam may use a different prosodic form), and allows for theological depth — each padhigam is a complete meditation on its subject. The Āchāryas wrote independent commentaries on individual padhigams, exploring their philosophical, devotional, and narrative layers.
