From The Oudumbara Vruksha (ficus glomerata) or Cluster fig tree is a variety of fig-tree held sacred in India. It is said to flower at intervals of long centuries.
It is a large tree that provides dense shade and edible fruit. Devotees of Lord Dattatreya, preferably observe their penance (Reading of sacred books, meditation, etc.) under this tree. Dried twigs of this tree are used in sacrifices. Its leaves are commonly used as cattle fodder. Oudumbara tree which is the favourite of Lord Dattatreya is used for the deeksha. Oudumbara Deeksha is a Mukthi-deeksha. Mukti Deeksha, in Hindu philosophy, is said to be a transfer of divine energy given by a Guru to a disciple.
