So Krsna says that there are two kinds of nature: superior nature, or higher nature, and inferior nature. Now, even the inferior nature... We take it for granted that there is something like inferior nature. Of course, this material energy, the material nature, is called inferior nature—inferior in the sense that matter has got no incentive. Without touch of spirit, matter cannot work. Therefore it is understood that it is inferior. But in the higher sense it is not inferior. How it is not inferior? Because it is emanation from the Supreme and you cannot separate this energy from the Supreme, and there is no difference between the Supreme and His energy.
Sakti-saktimator abheda. This is the Vedic injunction. Sakti, sakti means energy, and saktimat, saktimat means the person who has got the energy. So abheda, they are nondifferential. You cannot differentiate between the energy and the energetic. Just like electric powerhouse. The energy is electricity. Now, from the electricity energy we are working so many things. So far our household affairs are concerned, by the same electric energy we are getting heat and we are getting also cold. In the refrigerator we see everything is cold. In the heater we find everything is hot, warm. But the same energy is working. So one who knows that this is the electrical energy that is working in a different way, for him, there is no superior or inferior. That is called jnana. If we are on the platform of knowledge, then there is no distinction between matter and spirit.
And that knowledge we have to acquire. How we have to acquire? We must know it definitely that everything that is manifested... In the Visnu-Purana there is a nice verse which describes this energy and the energetic very nicely:
jyotsna vistarini yatha
parasya brahmanah saktis
tathedam akhilam jagat
And how they are acting? Just like the electric powerhouse is situated far away from your residential apartment, but from there the energy is being distributed and you are finding heat, cold, and so many things, electrically, you are working, so although the Supreme Lord is far, far away... Of course, He is not far, far away, but in our conception, in the material conception, because we cannot see... We are on a different planet. So by His energy He is not far away. Just like the sunlight, the sunshine, in the morning you find the sunshine is within your room, the sun is just within your room. It is actually. But still, the sun is 93,000,000 miles away from you. Similarly, in all circumstances we must understand that Krsna is, although far away from us, still, He is with us, within us. This is called knowledge. This is called knowledge.
And He says also in the Bhagavad-gita that sarvasya caham hrdi sannivistah: "I am situated in everyone’s heart." So just think how much nearest He is if He is sitting on my heart, and He is actually there, which is called Paramatma, or the Supersoul. So sarvasya, sarvasya means everyone’s, not only in human body, but in animal body, in the atoms also. Andantara-stha-paramanu-cayantara-stham. Paramanu means atom. He is situated. So practically, He is not far away. He is the nearest friend. He also claims in the Bhagavad-gita, suhrdam sarva-bhutanam: "I am the friend of everyone." So this knowledge, we have to acquire, that "We have got the greatest powerful friend in Krsna, and He is with me." This is knowledge.
