The first verse of the Dhammapada (“DUH-muh-puh-duh”) compares this concept to a wheel that follows the ox’s step. A common etymology of this concept compares it to a badly-fitting axle. The three forms of this concept include its vipariṇāma (“vip-puh-rin-NAH-muh”) form “of change” and its sankhāra form “of existence.” This concept is one of the three marks of existence, along with (-5[1])aniccā (“un-NITCH-chah”), or impermanence, and anattā (10[1])(“un-NUT-tah”), or a lack (-5[1])of unchanging self. (10[1])This concept is caused by taṇhā (“TUN-hah”), a term for craving or attachment, (10[2])and the cessation (10[1])of this concept is called (10[1])nirodha. (10[1]-5[1])After living (10[1])a sheltered life, (-5[1])Siddhārtha (-5[1])Gautama (10[1]-5[2])first learns about this concept (10[1]-5[1])after encountering (10[2])age, (10[1])disease, (10[2])and death. (10[1]-5[1])For 10 points, (10[1])name this characteristic of mundane life according to the first (10[1])of the Four Noble Truths, (10[1]-5[1])a sensation (10[3])that can (10[1])be ended by attaining nirvāṇa. ■END■ (10[4]0[1])
