By Swami Harshananda
Devasenā literally means ‘army of the gods’.
Later, Saṇmukha or Subrahmaṇya (also known as Kārttikeya) led the army of the Devas against Padmāsura and Tārakāsura and killed them. This pleased Indra who then gave Devasenā in marriage to him. Bṛhaspati is said to have performed the religious rites of the marriage. According to this story, the well-known festival day, Skandaṣaṣṭhī or Subrahmaṇya ṣaṣṭhī memorializes this marriage.
