meditation on the aspect of an object [e.g., meditating on impermanence] Comment: There are two types of meditation, meditation on the aspect of an object [e.g., meditating on impermanence] (don rnam sgom pa) and meditative cultivation of the aspect of a subject [e.g., meditatively cultivating compassion] (shes rnam sgom pa). The first means to meditate on an object, and the second means to meditatively cultivate a consciousness, an attitude.
