Kegavana is an Aramaic paragraph that is commonly recited in Nusach Sefarad on Friday nights after Kabbalat Shabbat and before the beginning of Ma'ariv (Barchu).
Is it better for one to stand or to sit while saying it?
As it is a meditation relating to Barchu and to receiving the additional neshama, it might be better to stand. But as it may be considered learning Torah (according to this answer), perhaps one should sit. What are the prevalent minhagim?
