According to the spirit of this age, women must advance and fulfill their mission in all departments of life, becoming equal to men.

They must be on the same level as men and enjoy equal rights.

This is my earnest prayer and it is one of the fundamental principles of Baha'u'llah.
Some scientists have declared that the brains of men weigh more than those of women, and claim this as a proof of man's superiority.

Yet when we look around us we see people with small heads, whose brains much weigh little, who show the greatest intelligence and great powers of understanding; and others with big heads, whose brains must be heavy, and yet they are witless.
Therefore the avoirdupois of the brain is no true measure of intelligence or superiority.
When men bring forward as a second proof of their superiority the assertion that women have not achieved as much as men, they use poor arguments which leave history out of consideration.

If they kept themselves more fully informed historically, they would know that great women have lived and achieved great things in the past, and that there are many living and achieving great things today.
Here 'Abdu'l-Baha described the achievements of Zenobia and other great women of the past, concluding with an eloquent tribute to the fearless Mary Magdalene, whose faith remained firm while that of the apostles was shaken.
