Vakra is a Sanskrit word meaning twisted, it is related to Lord Ganesha and his mantra.

Lord Ganesha has been acknowledged as the Remover of Obstacles and Lord of Success. The Sanskrit word ”Ganesh” comes from the word ”vighna”, which translates as obstacles, hurdles, hindrances, or impediments. There are 2 kinds of vighnas: external and internal. When we learn to remove the internal ”vighnas”, the external ones are consequently removed.
