Chagigah 19
Purification for non-sanctified purposes does not require intention; the inadvertent act of immersion is sufficient \u2022 Why is an immersion within a rainwater waterfall unable to purify? Why does a detached wave from the sea need 40 se'ah to purify a person according to the Shach, Taz, and Meiri? \u2022 What type of incidental water contact with fruits engender their susceptibility to ritual impurity? \u2022 Can one have intentions to achieve specific levels of purification while no longer immersed? \u2022 Is the first tithe equivalent to unsanctified products or does their higher level of sanctity require specific intentions to permit their handling?
