Granthi knots

The granthi knots are related to Kundalini. They cannot just be opened.

"Serving others is a completely satisfactory way to spend your life, but this service could become your cross to bear, where you hold resentment against others,
and view them as lesser beings."

This statement shows a total lack of understanding. It comes from ego.
Some people are born to serve without hesitation. It is the very reason they exist. Pisces and Virgo are two.

There is no cross. It is a natural act that gives joy. Obviously, it is also the case that 'lesser' has no place anywhere.
