this month is special because the uthiram nakshatram coincides with the full moon. this full moon signifies the marriage of parvati and parameswara (lord shiva), murugan and deivanai, and aandaal (also known as kothai) and rangamannar took place. on panguni uthiram, narayana marries komalavalli naachiyar and give his kalyana kola seva to his bhakthas. again, valmiki's ramayana says it is on this day and star that sita's marriage with rama was celebrated. from brahmanda puranam we learn that on panguni uthiram every holy water joins thumburu teertha (also spelt as tirtha), one of seven sacred tanks in tirupati tirumala.
