"Anxiety" & "Depression"
"Rang" word has many perspective in "GURU's BANI"
One perspective which relates to physical body color
"Gora" "white" / "Savla" or "Medium" / "Dark" or "Kaala"
European Asian and African has region relevance also
Many fall prey of racial discrimination. "Melonine"
chemical responsible for pigment color regulates tone with exposure to sunlight
Body color tone belongs to nature Reference:: Sikh Philosophy Network http://www.sikhphilosophy.net/gurmat-vichaar/37643-rang.html
"Body" needs limited exposure of light
"Light" required inside body needs control for its biochemical balance
"Body" receiving more sunlight are dark in color
"Body" receiving medium sunlight are medium in color
"Body" receiving less sunlight are light in color
and has variance with region
If European moves to Asian and African Region
They have to use "Sun Creams" to protect there skin when exposed to
sunlight, even player use that.
When this natural activity is disrupted
it cause disease "Phulwari" or "White Pigmentation"
People who have racial discrimination and long for fair color
applying creams/ointments for fairness are unaware
about cause of nature
