From /u/:
"Love
The very "mystery" that has eluded experts and researchers in various fields, and complete understanding of it continues to evade even modern-day science.
It is an emotional pattern viewable within the human brain through electrical signals and chemical action, often associated with particularly noticeable and incredibly strong reactions.
In the past, despite having a low link coefficient, through the use of LiNKER Amou Kanade was able to become a Symphogear user. The primary reason for this is the "hatred" she harbored toward the Noise that killed her father, mother and younger sister. Her will was brought to life by her thoughts of "it this will let me massacre those bastards!"
In this way, the chemicals secreted by the human brain, in addition to the explosive electrical signals they send, are occasionally able to exhibit effects similar to that of LiNKER. "Love" is much the same, when build up it can bring forth results comparable to that of miracles.
The feelings of Kohinata Miku, mainly her desperate wish of not wanting to lose Tachibana Hibiki, were warped by Dr. Ver and used to equip her with the Shen Shou Jing Symphogear.
"Love." A poetic word that can describe things which are precious and beautiful as well as people who embody kindness. However, just as it was the underlying cause of the Lunar Attack that occurred 3 months ago, love has bared fangs against humanity, even the entire world, countless times."
In other words, symphogears are powered by Love and/or Hate.
