I am researching the laws of the second day of Yom Tov in Golus. On one occasion, I found the text of the Shulchan Oruch Horav Orach Chaim 496 which states that someone not from Israel who is visiting Israel need keep only one day.
Together with this, I found text which suggested a reason for this relating to the emanation of the Yom Tov which in golus expands into two days.
Now I cannot find these texts.
Where online are the texts to which I refer?
