A few quotes from the Rabbi on 'Customs of Israel'
in which he encourages maintaining the custom of gathering at the baby's home on the eve of a circumcision
It is our custom to gather at the baby's home the night preceding the circumcision, and reading from the Lech Lecha portion of the holy Zohar, singing hymns and songs, and praising the Covenant-Maker, who has granted a male child to the parents. Far be it from us to forbid this, and would that this hallowed Jewish custom endure…
We found this hallowed custom in Siach Yaakov, the holy book by our Teacher, the divine kabbalist Rabbi Yitzhak Alfieh, of blessed memory, a Jerusalem sage and one of the Beit El kabbalists in our mighty city.
