The eighth symbol is Eight maids a milking
Matthew 5:3-10 describes Jesus’ famous Sermon on the Mount, which contained what are known as the Beatitudes. Jesus said:
Blessed are the poor in spirit, for theirs is the kingdom of heaven.
Blessed are they who mourn, for they will be comforted.
Blessed are the meek, for they will inherit the land.
Blessed are they who hunger and thirst for righteousness, for they will be satisfied.
Blessed are the merciful, for they will be shown mercy.
Blessed are the clean of heart, for they will see God.
Blessed are the peacemakers, for they will be called children of God.
Blessed are they who are persecuted for the sake of righteousness, for theirs is the kingdom of heaven.
The Beatitudes are at the core of Christ’s teaching. … The reward promised in each of the Beatitudes is primarily heaven. The Beatitudes reveal the goal of human existence, the ultimate purpose of human acts; God calls us to his own beatitude.
There is not much I can add to the above. The Beauties reveal the desirable qualities of the seeker who wish to attain enlightenment and a place in Heaven. I thought I take the time to clarify what Heaven really is. I understand that many, mostly religious. people believe that Heaven is a place where humans pass on to after life if on judgement day they are found deserving. In my understanding, however, Heaven is in the heart of the seeker. It is ever present and inviting and there is only a few things the seeker must do in order to ‘gain entrance to Heaven’ and experience happiness: see the list above.
Regarding the milking ladies, I can only guess how the milking ladies symbolize the 8 Beauties. My suggestion is that it has been believed that milk has beauty enhancing qualities. Cleopatra only washed in milk believing that it preserved her youth and beauty. The milking maidens also symbolize purity that is the ultimate goal of the seeker – to clean him/herself of the dirt of this world , to relieve all limitations and stand pure and clean so he/she can enter Heaven.
As I suggested before, Heaven is in each Heart. In order to enter Heaven, the seeker must enter Heaven he/she releases all bondage of this world through a rigorous practice of meditation/prayer and following the guidance that Jesus and other teachers before and after Him laid for all those to search for the Truth and ready to let go and enter the land of Joy and Happiness that is in our Hearts – the place where we meet God aka our Essence and the pure Love we all seek to experience.
