Wheat: Make from it some kind of pastry or dessert and reflect on Zohar, vol. 3, 188b. Then everyone should say the blessing, “borei minei mezonot.”
Olive: Reflect on Zohar 3, 247a and also on the Ra’aya Mehemna there. Then one of those present should say the blessing, “borei peri ha-eitz.” The kavvanah is simply YHVH.
Dates: Reflect on Zohar 3, 17a. Afterwards, one of those present who did not already eat from the previously blessed fruit says the blessing with the kavvanah, YHHV.84The twelve permutations of YHVH serve as kavvanot for the first twelve fruits that are blessed. Similarly, one person who has yet to partake says the blessing for each of the remaining fruits.
