Tara is said to be the Prajna of Buddha Amoghsiddhi. Tara is the embodiment of the air element and is thus green in colour. Tara is also called Irsyarati i.e. the nature of jealosy. When the defilement jealosy is transmuted it becomes all accomplishing wisdom (skt. Krityanusthan Jnana).

In Advayavajra Samgraha, she is said to be originated from the seed syllable Tam of golden green colour. Her recognition symbol is a green night lotus (skt. Utpala). She belongs to Karma family. She represents the enlightened activity of all Buddhas of three times. She too has many forms i.e. two armed, six armed and eight armed.
