The Book of Esther tells us that Haddasah is Esther.
Who is Haddasah and who is Esther?
Within our soul there is a Haddasah and there is an Esther.
There is the Light of Love and the Potency of Self-sacrifice.
When we live in the darkness of persecution or in the darkness of assimilation, the Light of Love (Haddasah) is extinguished, however, the Potency of the Soul (Esther) is awake.
It is Esther that resurrects Haddasah.
How does one connect with and actualize the Potency of the Soul? Through the power of the divinity of Torah-study.
