What is the psychological meaning of Linga ?
The psychological explanation of the symbol is that Linga is the cosmic soul having self-consciousness. The cosmic soul first vibrates in its being towards creation. The vibration is Nada, the first expression as Nama or name. From the Nada, proceeds the Bindu, dot or form. These two Nama and Rupa or Nada and Bindu are what is known as Pranava. The Bindu is the disc like base and Nada is the line supervening the base. The line stands on the Bindu like a cylinder with rounded top. This forms the Linga.
