Is there a Heavenly Mother?[BIO]
Does the Church teach doctrine about Heavenly Mother?
No, not very often. There is no specific canonized revelation that refers to Heavenly Mother, but prophets and apostles have acknowledged Her existence since the early days of the Church. More recently, The Family: A Proclamation to the World states that each person is the son or daughter of heavenly parents. The Church website also has an essay on "Mother in Heaven" and General Authorities have mentioned Her in conference talks.
Where did the "Heavenly Mother" idea in LDS theology come from?
It's unclear. In February 1844, The first recorded reference to Heavenly Mother was possibly in a poem written by W. W. Phelps[BIO] published in the Times and Seasons that referenced a "queen of heaven." In January 1845, Phelps referred directly to Heavenly Mother when he wrote "Thy father is God, thy mother is the Queen of heaven."
Did Joseph Smith ever teach about Heavenly Mother?
Probably, but there are no firsthand historical records that indicate that Joseph Smith taught the concept, however people who were close to Joseph Smith wrote about Heavenly Mother. Eliza R. Snow,[BIO] one of Joseph Smith's[BIO] polygamous wives, used the concept of Heavenly Mother in an 1845 poem "My Father in Heaven," which became the basis for the popular hymn "O My Father."
The most direct evidence that Joseph Smith taught about Heavenly Mother is a thirdhand report written over sixty years after Joseph's death. It stated that Joseph taught Zina D. Young[BIO] about Heavenly Mother in 1839.
Do we know anything about the character of Heavenly Mother?
Has anyone seen or heard from Heavenly Mother?
Possibly, but probably not.
Abraham H. Cannon[BIO] recorded in his journal that Joseph Smith saw Heavenly Mother. He said that Zebedee Coltrin,[BIO] Sidney Rigdon,[BIO] and Joseph Smith saw a vision of the Father, the Mother, and a young Jesus.[BIO] However, there are two other accounts of this vision recorded elsewhere that say it was a vision of Adam[BIO] and Eve[BIO] instead of Heavenly Father and Heavenly Mother.
Are there scriptural supports for Heavenly Mother?
Genesis 1:26-27 states, "God created man in his own image, in the image of God created he him; male and female created he them." According to one interpretation, "God" could refer to plural divine beings, and perhaps a "plural God" could imply a male and a female deity. Some scholars have speculated that a "plural God" and ancient Near Eastern symbolism could imply a male and female deity.
Latter-day Saint scholar Daniel Peterson[BIO] has theorized that Asherah, the Canaanite goddess referenced in the Hebrew Bible, should be understood as Mother in Heaven. He uses 1 Nephi 11 to support these claims. There are also Biblical references to a Queen in Heaven that some scholars think is Asherah.
Why don't Latter-Day Saints talk about Heavenly Mother more?
Probably because there is very little established information about her.

Where did the "too sacred to talk about" idea come from?
Not from any authoritative source. No statements from a General Authority that called for a "sacred hush" about Her has ever been found. Church leaders seem comfortable bringing up Heavenly Mother.
Does Heavenly Mother have a role to play in the Plan of Salvation?

Elder Jeffrey R. Holland said in General Conference, "To a Mother in Heaven, I say, 'Thank you for your crucial role in fulfilling the purposes of eternity.'" 
Is She a god?
Yes, probably. Latter-day Saint leaders have taught that She stands "side by side" with God the Father. Historically, Latter-day Saints have been conflicted on whether they recognize Her in the Godhead.

Probably not. This is not something that the Church, or its leaders, have ever taught. However, some Latter-day Saint scholars have speculated that it's possible that Heavenly Mother could be the Holy Ghost.

“I listen to a podcast called Talking Scripture. They said the O.T. once had many references to a divine feminine character, but they were removed during a Jewish reformation period. They point out that the O.T. still retains some oblique references to a mother in heaven.”

“I honestly very much dislike the idea of a heavenly mother. It seems very pagan. The Bible states repeatedly there is no God beside me. Meaning he is the one and only. Also with no actual teachings on it I feel it should just be left alone completely. That's just me though.”
“I just joined the church a few months ago so I never heard the concept of a heavenly mother. However, through out my life there have been times when I would pray for help relating to feminine issues and I was lead by spiritual direction. Many testimonies throughout my life.”
