vyabhicāra (‘transgression’) In general it means an evil act and in particular, adultery. The dharmaśāstras prescribe various kinds of punishment like amputation or even death. In logic it means a fallacy. If an effect is denied even though the cause exists, or, if an effect is accepted to exist in spite of the fact that the cause does not, it becomes the fallacy of vyabhicāra. vyādhi (‘disease’) Āyurveda or the science of health and longevity, categorises vyādhi or roga (disease) into four groups: āgantuka (coming from external sources or acci¬dents); śārīra (arising in the body due to the disturbance of the balance of the three humours viz., kapha, vāta and pitta); mānasa (of the mind, due to jealousy, anger, lust and so on); svābhāvika (natural due to hunger, thirst, oldage, sleep etc.). These diseases may be caused by faulty living as also by the karma of the previous lives. See also ADHI and ĀYURVEDA.
