“The design of the tes is like a pot, a vessel with an inverted rim, representing hidden or inverted good.
Another interpretation of the tes is that it represents a man bending his head to G‑d in prayer and thanks.
How are the two connected? We just explained the letter ches as representing the concept of marriage. After the union between husband and wife, then, G‑d willing, there’s a conception. The tes represents the hidden good that resides within the womb (the vessel) of the mother.
This hidden good is actualized through a person’s prayers to G‑d, asking Him for a healthy child.”
