“Worshipping any vigraha (murti), any statue of self-created vibrations of Mother Earth, people had big problems. They had to first of all do a meditation which was called as Sarvikalpa Samadhi, that means in that state you have to concentrate on such a statue, and then you go on looking at that statue, and try to raise your Kundalini.
And Kundalini used to come up to Agnya, but the jumping beyond the Sahasrara was an impossible task because one has to go from form to formless, and it was difficult to get out of form, to formless, and even to concentrate on abstract or formless was another impossible task, as Muslims did or many others tried to do.
Under these circumstances it was necessary that the formless had to take a form so that there were no more complications. As soon as you concentrated on the form, you became formless. (Like if you have ice before you, as soon as you start touching the ice, it melts away and you start feeling the cool, so the problem is very easily solved now.) “
Shri Mataji Nirmala Devi, Le Raincy (France), 18 June 1983
