The Gemara (Berakhoth 26:b) states that Yis-haq Abinu, 'a"h, instituted Tefillath Minha, the afternoon prayer. Yis-haq Abinu went out to pray in the field, and as the verse continues: "he lifted up his eyes and saw camels approaching". This was Eli'ezer's caravan returning from Haran with Yis-haq Abinu's future wife, Ribqa (Rebecca).
Ba'al Hatturim comments on the juxtaposition of Yis-haq Abinu's prayer and Ribqa Immenu's arrival immediately after his prayer. He brings out the concept that we should pray to G-d to help us find our soul mate.
This may sound like an obvious and plain idea, which we all know. I would like to share with you the words of Hakham Mordechai Eliyahu, 'a"h, who expounded on this point. He comments that there are those who say that people who have difficulty in finding their Shiddukh, their soul mate, should be particular about reciting the Minha prayer. This is a special Seghulla, a good omen, for finding their mate. He advises all those who are searching for their Shiddukh, to refrain from quick fixes and not get carried away by all kinds of new "Seghulloth". Rather, Hakham Mordechai Eliyahu, 'a"h, recommends adopting the craft of our forefathers: Tefilla, prayer! Particularly, Tefillath Minha, which is an incredible Seghulla.
