Zohar Ki Tisa
Rabbi Yosi tells Rabbi Echa that while he was walking on the way, he saw and listened to Rav Hamnuna Sava discussing a study related to the End of Days. He was happy and made a knot on his garments to so he will never lose this study.
Rabbi Echa said that a holy thing like this came from a holy light and how blessed is the generation that great pillars sustain the world. He continued to say that if rabbi Yosi made one knot on his garments, he will make 30 or 40 knots in his pocket.
To understand their words and the Zohar in generals we need to understand the terms the Zohar uses in describing different situations.
The garment is the surrounding light of a person and a ‘knot’ is a strong connection or a transformation of the study into light that expands the surrounding light and stay forever with the person even if the physical garment is worn out and thrown away.
Many times in the Zohar we read that the students are walking on ‘the way’ and different things happen to them. ‘The way’ is a high spiritual study that takes the students on a spiritual path of study. In the study of Rabbi Yosi he sees Rav Hamnuna Sava that had a soul from the world of Atzilut. The Holy Ari in the gate of Reincarnations reveals that Rav Hamnuna had a spark of the soul of Moses.
The ‘pocket’ of Rabbi Echa is the aspect of inner light of the garments that is closer to the soul.
All of our studies become connected to our surrounding light. With acts of prayers, Tzedakah and sharing we internalize the outer/surrounding Light into our vessel.
