Next year’s manual for Relief Society/Priesthood will be Gospel Principles, and chapter 2 begins with the following quote:
“All men and women are .Â .Â . literally the sons and daughters of Deity.Â .Â .Â . Man, as a spirit, was begotten and born of heavenly parents, and reared to maturity in the eternal mansions of the Father, prior to coming upon the earth in a temporal [physical] body” 
The concept of Heavenly Parents alludes to the teaching within the church that there is a Mother in Heaven. I went over a brief survey of statements regarding Heavenly Mother, mostly from the church website and magazines, and wanted to put up some characteristics that have been taught about her by prominent church members.
First, she was involved with Heavenly Father in the pre-mortal world with the teaching of spirits.  Had we not known in our pre-mortal existence that we could become like our Mother in Heaven, we never would have come.  Her glory was like the Fatherâ€™s Glory, and she was â€œside by side with Himâ€  Further She is â€œequally exaltedâ€ with Heavenly Father.Â  She was Essential to Him.  She has endowed her special traits and attributes upon her daughters, such as love, charity, and faithfulness. Coarseness and vulgarity is contrary to Her nature.  She is the â€œultimate in maternal modesty, of the restrained queenly eleganceâ€ and Her Influence upon us will be great if we live our lives here â€œso as to return thereâ€  She values her children â€œbeyond any measureâ€  In the grand order of things, we do not pray to her, but this lack of prayers in no way denigrates or belittles her  This may be perhaps because she is in perfect unity with her spouse, and thus prayers to him are equal to prayers to her.  Alternatively, she is prayed to (sort of) each time the Song â€œOh My Fatherâ€ is Sung.
There is some disagreement as to the origin of teachings regarding Heavenly Mother within the church, with possible alternatives being that Joseph received a revelation and shared it with Zina Huntington, that Joseph Revealed it to Eliza R. Snow, and that Eliza, having claim to prophecy in her own right received it directly from God. Perhaps all three occurred.  Alternatively, other members has referred to teaching of her as a case of “over-belief” (sorry, no citation available)
In recent years, the church has publicly clarified some points in regards to our Mother in Heaven, noting that she is not referred to as â€œThe Motherâ€ among church members and acknowledging that there are no teachings about her in Latter-day Saint Scripture.  This should not concern members however, as she is mentioned in conjunction with the Father as Heavenly Parents in the First Presidency Declaration regarding Families , and Joseph Fielding Smith noted â€œthe fact that there is no reference to a Mother in Heaven in either the Bible, Book of Mormon or Doctrine and Covenants, is not sufficient proof that no such thing as a Mother did exist there.â€  In any case, while the Mother may seem veiled to us, the typical saint trusts that God has his reasons for revealing as little as he has.  And in any case, the Lord has provided for us an ample Role Model and Confidant for both Sexes in the Savior Jesus Christ.
