Form

The aggregate of forms (Skt. rūpa; Tib. གཟུགས་, zuk, Wyl. gzugs) is the first of the five aggregates.

This aggregate can itself be divided into fifteen:

• 1-4: the four causal forms, which are the four elements of earth, water, fire and wind.
• 5-9: the five sense objects of visual form, sound, smell, taste and texture.
• 10-14: the five sense faculties of eye, ear, nose, tongue and body.
• 15: the imperceptible form. This can further be subdivided into five: form of particles, spatial form, form resulting from a fully taken promise, imagined form and mastered form.
