Gratitude falls under the virtue category of Transcendence. Transcendence describes strengths that provide a broad sense of connection to something higher in meaning and purpose than ourselves.
There are two types of gratitude:
Benefit-triggered gratitude= the state that follows when a desired benefit is received from a benefactor.
Generalized gratitude= the state resulting from awareness and appreciation of what is valuable and meaningful to yourself.
There are two stages of gratitude:
Acknowledging the goodness in your life.
Recognizing the source of this goodness is outside yourself.
