In Greco-Roman mythology the peacock is identified with Hera (Juno) who created the peacock from Argus whose hundred eyes (seen on thetail feathersof the peacock) symbolize the vault of heaven and theeyesof the stars.
In Hinduism the peacock is associated with Lakshmi who is a deity representing benevolence, patience, kindness, compassion and good luck.
Similar to Lakshmi, the peacock is associated with Kwan-yin in Asian spirituality. Kwan-yin (or Quan Yin) is also an emblem of love, compassionate watchfulness, good-will, nurturing, and kind-heartedness. Legend says she chose to remain a mortal even though she could be immortal because she wished to stay behind and aid humanity in their spiritual evolution.
Themes of renewal are also linked to alchemical traditions, as many schools of thought compare the resurrecting phoenix to the modern-day peacock. Along these lines, the peacock is a colorful symbol of transformation. Like the phoenix, the alchemy peacock can remind us that we can rise out of our darkest moments. It's a metaphor that speaks about dying to the ego-self, and being reborn into a new life of awareness, spirituality and illumination.
