Answer: Yes. The language of Kabbalah is most appropriate for our times because it is a precise language. When a person uses it, he helps shape his emotions correctly.
A person wakes up and summons the influence of the higher forces upon himself with feelings, not through words. When these feelings are processed, spoken, and shaped internally into particular patterns appropriate for the structure of the spiritual world, they acquire an absolutely precise manner of expression in spiritual forms. So he awakens and summons upon himself the influence of the Upper Light, the Ohr Makif (Surrounding Light) with maximal intensity.
If we are talking with the Creator, meaning with the higher level, it is necessary to speak in Hebrew.
