The ninth type of music is with ‘joy’ (rinah). And this is: (Ps. 33:1) Rejoice (rane-nu) O righteous-ones in Y”Y. And this is the level of the Righteous-One (Yesod), the ḥaiy (life-force) of the worlds. From there, comes joy – and through it is redemption! It is this that is written: (Jer. 23:5)... the righteous plant∞tzemaḥ... (Zech. 6:12)... and from beneath him it will sprout∞yitzmaḥ... Beneath him, specifically – that which is ‘the tenth’ of everything (Malkhut).
And ‘the Righteous-One’ (Yesod) takes from the left, and ‘the Middle Pillar’ (Tipheret) from the right. It is this that is written: (Deut. 33:2)... from His right-hand a fiery law for them.
