Our sages explain that life is intrinsically pure and everything related to it must be pure. In contrast to death that represents exactly the opposite. In this sense, our life becomes impure when we taint it with all that is against its integrity, dignity, honor, and goodness.
Consequently, purification is the way to keep love always present in our lives. We must realize that the message here is to understand impurity as the result of inviting anything that represents the opposite of life. We are truly alive when we live in the ways of goodness, the pure ways the Creator commands us to live by.
True life is sustained by the waters of God's love. Our mystic sages teach that Aaron, Miriam and Moses represent our highest awareness of the Creator, what we call the awareness of God's ways and attributes. Aaron is our wisdom, Miriam our understanding, and Moses our knowledge.
As long as these qualities of our intellect are permanently aware of the Creator in our lives and in all Creation, we are truly alive in the material world. If one of these qualities is missing, we feel disconnected from God's love.
The narrative continues with the conquest of the promised land, and the events are related to the main message of this portion, purification. We have said the "nations" that occupied this land represent negative traits and trends that Israel must avoid in order to remain sacred to the Creator.
We must realize that when we are dealing with negative thoughts, emotions, feelings and passions, we risk the goodness of love as the inherent quality of life. Hence, we have to turn away from negativity because in it we can't get through anything good.
In order to avoid the negative aspects of consciousness we must be determinant, and fully commit every dimension of our life to God's ways and attributes. When we allow them to lead, we are able to transform negative traits into qualities that we dedicate to fulfill His will. God's love does this transformation.
This transformation does not make sense as long as some aspects of consciousness are still attached to lower emotions and materialistic desires as some of ego's negative perceptions that taint the purity of life as the gift of God's love.
The illusion of separation in ego's individualistic agenda, represented by the snake, again proves to be the main tainting trait that causes death before the eyes of love.
The portion ends with the verse, "The children of Israel journeyed and encamped in the plains of Moab, across the Jordan from Jericho." (22:1), where the dangers of falling into negative thoughts and emotions are reminders that our true choice in order to consecrate life is love.
