Why Must Tefillin Stay On Until After Aleinu —And Can They Be Removed Early for Health or During Keri'at HaTorah ? The ideal practice is to wear Tefillin throughout the entire Shaharit service—from the beginning of the Berachot until after Aleinu . This wasn't just a stringency of the righteous—many authorities consider it a halachic preference, rooted in the structure of prayer and the meaning of Tefillin. Why Keep Tefillin On Until After Aleinu ? The Tefillin reflect our bond with Hashem—physically, spiritually, and publicly. The Mekubalim teach that each section of Tefilla corresponds to higher and higher spiritual worlds. Keeping the Tefillin on through Aleinu ensures the sanctity flows through the entire process of ascent. Removing them before Aleinu may disrupt the flow of the Misva . It also signals a "spiritual descent" before the Tefilla experience is complete. What If Someone Has Discomfort or a Medical Issue? Sometimes a person may want to remove the Tefillin earlier—after the Amidah, or even sooner—because of: Headaches Tightness from the straps Nausea or stomach weakness Skin sensitivity or pressure points In these cases: It is 100% permissible to remove the Tefillin early. Hacham Ovadia Yosef writes that the Misva of Tefillin must be done with joy and dignity , not with discomfort or pain. One should not push through physical suffering just to complete the ideal time frame . Should One Remove Tefillin Before or During Keri'at HaTorah ? Many people remove their Tefillin before the Torah reading on Mondays and Thursdays. But this is not ideal unless the synagogue has a strong custom. If possible: • Keep Tefillin on through Keri'at HaTorah . • The sanctity of the Tefillin matches the holiness of the Torah reading. • One who receives an Aliyah should wear Tefillin while standing next to the Sefer Torah. However: If it feels uncomfortable or awkward (especially if the community expects Tefillin to be off), one may remove them just before the Aliyah. Ideally, step to the side or wait until the Sefer Torah is covered before removing them. Summary: • Tefillin should remain on through the entire Tefilla and Aleinu . • Removing early is allowed for valid health or comfort reasons. • Tefillin should ideally stay on through Keri'at HaTorah unless there's strong reason or local custom to remove them.
