Deepak Chopra Explains that there is concept of one reality

Example 1 : caterpillar turning into butterfly

what goes on invisibly inside the chrysalis remains deeply mysterious. The caterpillar’s organs and tissues dissolve into an amorphous, souplike
state, only to reconstitute into the structure of a butterfly’s body that bears no resemblance to a caterpillar at all.

Science has no idea why metamorphosis evolved. It is almost impossible to imagine that insects hit on it by chance-the chemical complexity of turning into a butterfly is incredible; thousands of steps are all minutely interconnected. (It’s as if you dropped off a bicycle at the shop to be repaired, and when you came back the parts had become a Gulfstream jet.)

But we do have some idea about how this delicate chain of events is linked. Two hormones, one called juvenile hormone, the otherecdysone, regulate the process, which looks to the naked eye like a caterpillar dissolving into soup. These two hormones make sure that the cells moving from larva to butterfly know where they are going and how they are to change. Some cells are told to die; others digest
themselves, while still others turn into eyes, antennae, and wings. This implies a fragile (and miraculous) rhythm that must remain in precise balance between creation and destruction. That rhythm, it turns out,depends on day length, which in turn depends on the earth’s rotation around the sun. Therefore, a cosmic
rhythm has been intimately connected to the birth of butterflies for millions of years.

Science concentrates on the molecules, but this is a striking example of intelligence at work, using molecules as a vehicle for its own intent. The intent in this case was to create a new creature without wasting old ingredients. (And if there is only one reality, we can’t say, as science does, that day length
causes the pupa’s hormones to begin the metamorphosis into a butterfly. Day length and hormones come from the same creative source, weaving one reality. That source uses cosmic rhythms or molecules as it sees fit. Day length doesn’t cause hormones to change any more than hormones cause the day to change—both are tied to a hidden intelligence that creates both at once. In a dream or a painting, a boy may hit a baseball, but his bat doesn’t cause the ball to fly through the air. The whole dream or painting fits together seamlessly.)

Example 2: How insects learned to fly

Two chemicals called actin andmyosin evolved eons ago to allow the muscles
in insect wings to contract and relax. Thus, insects learned to fly. When one of these paired molecules is absent, wings will grow but they cannot flap and are therefore useless. Today, the same two proteins are responsible for the beating of the human heart, and when one is absent, the person’s heartbeat is inefficient and weak, ultimately leading to heart failure.

Again, science marvels at the way molecules adapt over millions of years, but isn’t there a deeper intent? In our hearts, we feel the impulse to fly, to break free of boundaries. Isn’t that the same impulse nature expressed when insects began to take flight? The prolactin that generates milk in a mother’s breast is unchanged from the prolactin that sends salmon upstream to breed, enabling them to cross from saltwater
to fresh. The insulin in a cow is exactly the same as the insulin in an amoeba; both serve to metabolize carbohydrates, even though a cow is millions of times more complex than an amoeba.

To believe in one reality that is totally interconnected isn’t mystical at all, it turns out.
