The Ground of Dzogchen is described as being endowed with three qualities―essence, nature and compassionate energy. The third quality of the Ground is its compassionate energy (Tib. ཐུགས་རྗེ་ . Wyl. thugs rje).
Just as the sky and sunlight are indivisible, so the empty essence and cognizant nature are always a unity. This inseparability or unity is called ‘compassionate energy’, the manifestation of the compassionate energy of the enlightened mind.
This unceasing compassionate energy is described as:
—unconfined, unobstructed, —and all-pervasive.
It too possesses three wonderful qualities:
—the wisdom that knows, —the compassion that is loving and caring,
—and the power that is able to liberate, protect, and benefit beings and fulfil the enlightened activity of the buddhas.
