Then I changed focus of my investigation. The next question I posed was with what substance did Creator create universe? I could not find a satisfactory answer even for that question.

Therefore next question was "What was there for Creator to create with?" I realised that before anything was created, only Creator existed and nothing else. This is axiomatic and needs no proof. The Creator had only His/Her own substance. There was nothing else in universe. Therefore he had to create with His own substance.

That means substance of creation and substance of Creator is same. If substance is same, nature must be same. Then nature of tangible, observable and knowable creation, is nature of intangible, invisible, unknowable Creator. By studying nature of creation, I will know nature of Creator. This was an exhilarating idea and I was overjoyed. But very soon it ended in disappointment.

For there are millions of substances in universe, organic, inorganic, chemical or physical, natural or artificial, solid, liquid, and on and on and each substance has dozens of natures or qualities. Which nature of which substance am I to study? I found it impossible to study all natures of all objects in universe in my life time. I was about to give up in disgust.

Then an intuitive information appeared. Since substance is same for all creation there must be a common nature among them. If so, what is that common nature? So, I looked for common natures and I found many common natures. There were many substances with common natures such as liquid, solid, smooth or rough, hard or soft, natures common to many substances but I could not find one nature common to all substances.

Finally, when I was about to give up in disgust, as if by providential nudging, I hit upon gravity. Gravity is attraction or love. That could be nature of creator!
