View source for three types of teaching

From the meaning explained in ''The Wisdom Essence'' there are [[three types of teaching]]:  tantras, statements, and instructions. '''''Tantras''''' which manifest as the '''natural sound of dharmata''' from the [[Lord of the Circle]] and are like a treasury of jewels contained within the chest of the [[Six limits and four modes]]; the '''''statements''''' by the lords of the [[ten bhumis]] which clarify the meaning of the tantras, fully disclosing their secret significance, and are like a key to this treasury; and finally, the '''''instructions''''' in the key points of the tantras by the [[vidyadhara]]s that condense these to be applicable for worthy people and are like one's heritage being placed in the palm of one's hand.
