The prophet Elijah stated, “Does it not emerge that the wife illuminates her husband’s eyes, and puts him on his feet? A wife illuminates her husband’s eyes by enabling him to see things beyond his natural perspective. She stands him on his feet by preventing him from tripping over some unseen stumbling block” (Tractate Yevamot 63a).

That’s why the Talmud states elsewhere (Tractate Sanhedrin 22a), “A man’s world is darkened after his wife dies and his steps become shortened. For he is deprived of his complementary relationship.”
