Max Landis calls Superman:
a person who could do anything, and chooses to do the right thing out of kindness, not obligation
A Buddhist would call that बोधिसत्त्व.
Superman's moral judgment is perfected, he feels no fear, his compassion is limitless, and he is empowered with siddhis of every real or imagined human capacity to a divine, superhuman degree. He draws his powers from the golden light of the Sun.
Those who know the chakra system might call this anāhata, the heart.
But Superman is a Western god, transmitted to us originally by a couple of Jewish kids from the holy city of Cleveland, so his symbolism is best understood in terms of the Hermetic qabalah. In that system tifareth, which means “beauty” (whose number is six and planet is the Sun, color is yellow, metal is gold) closely mirrors anāhata. Superman is traditionally depicted wearing the blue of chesed (“mercy”, the protective and sustaining sphere, corresponding to four, Jupiter, and tin) trimmed in the red of gevurah (“strength”, the fierce and active counterpart to chesed, corresponding to five, Mars, and iron). Over his heart there is an emblem which shows his sigil over a field of the yellow of tifrareth, bound within a five-sided shield in the red of gevurah.
He bears the Hebrew angelic name Kal-El, “The Grip of God”. His father bears the name Jor-El, “Teacher of God”; his mother bears the name Lara, “Of The Initiation”; his cousin Supergirl bears the name Kara Zor-El, “Call To God's Stranger”.
The aspirant may benefit from meditation on the significance of these colors, sigils, and names.
