Good morning, esteemed friends. Today, we gather to delve deeper into the nuances of halacha, particularly focusing on the practice of immersing hands in the mikveh for netilat yadayim. We previously established that at the seashore, it is permissible to dip one's hands in the ocean, and we discussed that the blessing recited is 'al netilat yadayim.' Moreover, we examined the concept of a maayan, where one does not require forty se'ah of water to perform this ritual, as long as the hands are submerged adequately. In contrast, we encountered a machloket regarding the mikveh, specifically whether forty se'ah is necessary. Ultimately, we concluded that one could be lenient even if the mikveh does not contain the requisite forty se'ah for netilat yadayim.
Now, let us turn to halacha thirty, where we explore a new topic grounded in the Shulchan Aruch. This halacha states that forty se'ah of drawn water, known as mayim she'uvim, is considered invalid for a mikveh. Mayim she'uvim refers to water that is drawn with a container, which disqualifies the mikveh. Ideally, a mikveh should consist solely of rainwater, collected naturally without any vessel intervening. You may wonder about the water in our mikveh, which is often filled through pipes; however, the water in the pool connects to a bor filled with forty se'ah of rainwater. This connection ensures that the water in the mikveh meets halachic requirements.
It is crucial to understand that drawing water with a container is not permissible when it comes to filling a mikveh. For instance, if it rains and one attempts to catch rainwater in buckets and then transport it to fill the mikveh, this is also considered mayim she'uvim and is invalid. Instead, we utilize a system where water flows directly from the roof through pipes, ensuring that it falls naturally from the heavens into the bor, thus preserving its halachic status.
Next, we encounter another concept: mayim nimshachim. If someone pours forty se'ah of water from a container into a mikveh, this is classified as mayim she'uvim and is not acceptable. However, if the water is poured onto the ground and flows into the mikveh, we enter a debate between the Rambam and the Ra'avad regarding its validity. The Rambam argues that because this is an act of immersing, it must occur in a body of water that can purify the entire body. Thus, he deems it invalid. Conversely, the Ra'avad contends that since the tumah (impurity) of one's hands is a rabbinic institution, one can purify through immersion in such water.
We find ourselves at a crossroads in determining whose opinion to follow. The Shulchan Aruch presents both views without explicitly endorsing one over the other. The text states that forty se'ah of mayim she'uvim in the ground is not suitable for the Rambam, while the Ra'avad permits it. The ambiguity in the Shulchan Aruch leads to extensive discussion among scholars regarding Maran's stance. Some posit that Maran typically aligns with the second opinion when both are presented, while others argue that the mere citation of the authorities indicates a preference for the Rambam.
In practical terms, we generally follow the opinion of the Rambam. Therefore, if someone were to immerse their hands in a body containing forty se'ah of mayim she'uvim, it would not suffice unless no other water is available, in which case one should refrain from reciting the blessing.
Let us now revisit the scenario where water flows into the mikveh from the ground after being poured. If someone fills a mikveh with mayim she'uvim but allows it to flow into the mikveh naturally, the Rambam would consider this acceptable. This distinction is vital, as it affects the halachic status of the water used for netilat yadayim.
Moving on, we encounter a practical question regarding immersing hands at the ocean. The Shulchan Aruch advises against taking water with one hand and pouring it onto the other, as this does not fulfill the requirements of either netilat or tevilah. Instead, one should dip both hands directly into the water. This instruction is clear: one must engage in the proper act of immersion to achieve the desired halachic outcome.
Another question arises about mixing methods. If one uses a cup of potable water for netilat yadayim with one hand and immerses the other hand in the ocean, the Shulchan Aruch states that both hands are rendered pure. Each method works independently, allowing for a valid combination.
When immersing hands in the ocean, the question of whether to follow the same procedures as with a cup arises. The Shulchan Aruch clarifies that one need not immerse hands multiple times when using the mikveh. Once immersed, there is no requirement to dry the hands, as the immersion itself suffices. This contrasts with the traditional cup method, where drying is part of the mitzvah.
However, some authorities, such as the Kaf HaChayim, recommend additional precautions, including immersing hands three times and rubbing them together. This reflects the influence of Kabbalistic practices on contemporary halachic observance.
In conclusion, we must remain vigilant in our observance of these halachot, ensuring we understand the distinctions and rulings that govern our practices. Whether we are at the ocean or using a mikveh, we must approach these rituals with intention and care, adhering to the halachic guidelines that have been established through generations of scholarship.
