Lord Krishna`s peacock feathers on his crown are called Mayur pankh in Hindi and Sikhipincham in Sanskrit.

LEGEND SAYS

When Krishna was playing his flute in the Govardhan hills, the sweet melody that poured out caused the peacocks dance in joy and excitement. They spread their feathers at the end of a long dance, and the king Peacock donated his feathers as a gift with great humility. The lord received it and wore it as a decoration.

KRISHNA`S MAYUR PANKH

• It is very rare in nature. The eyes in the feathers are seen on both the sides, which commonly do not occur. The feather has extraordinary powers, which gives hypnotizing powers to the wearer.
• When one worships Krishna with the feathers on his crown, one is blessed with auspiciousness, wealth, health and transcendent knowledge.
• They represent divine love that enters the human heart and fills one`s entire being in ecstasy. It also reminds us of the romantic love shared between Krishna and Radha. The feathers are always in the direction of Radharani. It is said Lord Krishna cleanses the holy feet of Radha with Peacock feathers, during their playtimes in Vrindavan.
• It is a symbol of beauty and knowledge. The eye in the feather represents the divine wisdom or the third eye of Krishna. It helps one attain the supreme knowledge of the self. It symbolically states that wisdom of the mind and love of the heart makes one existence whole and for this blessed state, it is very important to worship the Lord adorned with his feathers.
• The feather protects one from evil eye and destroys all negativity like anger, greed, jealousy and removes poisons.
• The feathers stand for beauty, richness in life, felicity and joy. The dark colors in it stand for sorrow, sadness and the bright colors for happiness, symbolizing that life comes with both happiness and sorrow and when one worships Krishna with peacock feather; one attains equanimity of mind, accepts life and learns to surrender to the lord.
• The brightness of the feather is due to the presence of barbules that help reflect light and Krishna`s pankh have barbules on both sides making it highly divine in nature. The barbules help the colors to shimmer and different hues appear at different angles.
• The feathers have thousand eyes, which symbolize as a vault of heaven and eyes of stars and it`s iridescent coloring is a gift from Lord Indra as an act of compassion to the bird.
• They also have the power to do away bad influences of the planets. Grace of both Radha and Krishna descends on worshipping this form of Krishna.
