Panguni Uthiram is a day of importance to Hindus especially those who belong to Tamilnadu. It falls on the day the moon transits in the asterism of Uttara-phalguni or Uthiram in the twelfth month of the Tamil solar calendar i.e. Panguni (March-April). It is also the full moon of the month of Panguni and 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 Deyvaanai, and Aandaal and Rangamannar. On Panguni Uthiram, Murugan married Kamalavalli Naachiyar. Also Valmiki's Ramayana says it is on this day and star that Sita's marriage with Rama was celebrated. The day is intended to underline the glory of grahasta dharma (or the married life of a householder). The Almighty manifests in the marital state as Uma Maheswara, Sita Rama, and Radha Krishna. Devotees celebrate this day when the Lord, in both Shiva and Vishnu temples, appears to devotees in his married state.
Devotees flock in hundreds to the all Murugan temples during the Panguni Uthiram festival, which is celebrated in March every year. It is the Jayanti (Day of Incarnation) of Lord Ayyappan. It is also an important festival day for Lord Subramanya (Muruga), as it is on this day that Sri Valli married Lord Subramanya. On this day Goddess Mahalakshmi incarnated on earth from the ocean of milk (after the ocean was churned by the Gods and the demons) and hence it is celebrated as Mahalakshmi Jayanti. Goddess Parvati in the form of Gowri married Lord Siva in Kanchipuram and hence this day is also celebrated as the Gowri Kalyanam.Panguni Uthiram is a famous festival and special to Murugan devotees.
'Muruga' literally means - The Beautiful One. Where there is beauty, love shines, and where there is love, truth radiates. When we seek the truth, we get freedom. Lord Muruga is a symbol of eternal youth, wisdom and liberation. Muruga is the essence of the Trinity. 'Mu' stands for Mukunda (Vishnu), 'Ru' for Rudra (Shiva), and 'Ka' for Kamala (Brahma), therefore Muruga represents the three divine functions - creation, protection and destruction.
The divine force of Panguni Uthiram can blow away the misunderstandings & troubles in a marriage and paves the way for a happy married life.
