It is the tree of creation described in the Gita. It is the cosmic tree through which creation descends into Ignorance. The mountain is the reverse movement of aspiration and ascension, a reverse movement which leads one out of the Ignorance towards freedom from Ignorance, Moksha. The juxtaposition of the two images means that your soul is being given a choice to either remain entangled in the fields of ignorance or else to ascend the mountain leading to inner freedom through the awakening and ascension of aspiration.
Affectionately,
Alok Da
