내 신부야 네 입술에서는 꿀 방울이 떨어지고 네 혀 밑에는 꿀과 젖이 있고 네 의복의 향기는 레바논의 향기 같구나

And this is [the meaning of] "sweetness drops from your lips, bride, [milk and honey are under your tongue] etc" (Songs 4:11) - also a hint to those three levels. "Sweetness drops" is a hint to the level of awe, [since] "myrrh drops" (Songs 5:13) is explained by our sages z"l with "do not read myrrh but etc" (Shabbat 30b:6). And "your lips bride" is a hint to the level of love, like a bride is beloved by her fiance. And "honey and milk under your tongue" is a hint to the third level, that all one's deeds are like honey and are splendid for all people.

The first aspect, is when one sees the Tzaddik, as is written (Isa. 30): "but your eyes shall see your teachers;" and this aspect annuls the bad traits, that are drawn from the two elements inanimate and vegetable, i.e. depression and its derivatives and evil lusts, for the Tzaddik of the generation is called Mother, because he nurses Israel in the light of his Torah, and the Torah is called milk, as is written (Song 4): "honey and milk are under your tongue." And this we see tangibly, when an infant is sad and lazy, when he sees his mother he awakes in great haste towards his mother, i.e. to his root. Also we see tangibly, when a child is busy with his things of nonsense, even though he has great lusts for this, despite this when he sees his mother, he throws all his lusts behind his shoulders and draws himself to his mother. Hence, the evil traits of the two elements inanimate and vegetable are annulled through seeing the face of the Tzaddik.
