Describe the Twelve Links.

Of the twelve links, the first is ignorance, old age and death. The second is volitional action--"formations, impulses, motivating energy or, with lack of understanding, anger or irritation. The third is individual, collective, mind and store consciousness, which may be filled with "unwholesome and erroneous tendencies" connected with ignorance. The fourth is name and form, or the mental and physical elements. The fifth link consists of the six senses that come into contact; the seventh link is feelings, the eighth is craving, the ninth is grasping, the tenth is "coming to be," the eleventh is birth, and the twelfth link is old age and death. Each link is interconnected with the other and each "conditions" the next. Ignorance leads to volitional actions, which lead to consciousness, which is connected to mind-body, and so on.
