Asceticism denotes a life which is characterized by refraining from worldly pleasures (austerity). Those who practice ascetic lifestyles often perceive their practices as virtuous and pursue them to achieve greater spirituality. Many ascetics believe the action of purifying the body helps to purify the soul, and thus obtain a greater connection with the Divine or find inner peace. This may take the form of self-mortification, rituals or harsh renunciations of pleasure. However, ascetics maintain that self-imposed constraints bring them greater freedom in various areas of their lives, such as an increased ability to think clearly and resist potentially destructive short term impulses. ***************************************** The term "minimalist" can also refer to anything which is spare, stripped to its essentials, or providing only the outline of structure, independent of the particular art movement, and "minimalism" the tendency to reduce to fundamentals. It is sometimes applied to groups or individuals practicing asceticism and the reduction of physical possessions and needs to a minimum.
an 'ism' is a thought, idea, or belief. Nobody here is an 'asceticism'. Just thought I'd share that piece of knowledge with you.
