Like Tchenrezig, Tara is a yidam (a symbol upon which one meditates). This symbol represents the wisdom that liberates every being and has thus a feminine representation. She is the representation of pure and non-dual understanding of the nature of mind, she is the source or mother of spiritual realisation.elle est la source ou la mère de la réalisation spirituelle. The green Tara represents the feminine, acting compassion and the enlightened activity. The white Tara is a long life symbol.
