there are two kinds of exultation or joyousness: the calm variety (called a vibration or sighing or intercession of the Spirit), and the great exultation of the heart — a leap, bound or jump, the soaring flight of the living heart towards the sphere of the divine.
The Philokalia establishes a formal pneumatic typology of joyousness, distinguishing a quiet vibratory form from a more dramatic upward flight of the heart empowered by the Holy Spirit.
