As the topmost planet within this universe is called Brahmaloka, similarly, in the spiritual sky, there is the topmost planet which is called Goloka Vrndavana. That is Kṛṣṇa's place. Kṛṣṇa is there. But He can expand Himself by His different types of energies and by His different types of incarnations. It does not mean that when Kṛṣṇa was present on this planet, Kṛṣṇa was absent in Goloka Vrndavana. No. It is not like that. Just like I am now present here, I am absent in my apartment. Kṛṣṇa is not like that. Kṛṣṇa can be present everywhere; at the same time, He can remain in his own abode. That is described in the Brahma-samhita: goloka eva nivasaty akhilātma-bhūtaḥ (BS 5.37). Although He is in his abode, which is known as Goloka Vrndavana, He can expand Himself everyone... Everywhere. And actually He has done it. So we must know how He has expanded. In which way He is in contact with us. That is the science. In Bhagavad-gītā, these things are explained.
So Kṛṣṇa is addressed here as Paramdhāman. The resting place of everything. Everything is resting. Kṛṣṇa also says, mat-sthāni sarva-bhūtāni (BG 9.4). Everything, material manifestations, is resting on him. Na cāhaṁ teṣv avasthitaḥ - but I am not there. These contradictory things. Everything is resting on him, but I am not there. But it is not contradictory. It is very simple to understand. Just like, all the planets, they're resting on sunshine. But the Sun is far away from the planets. Some millions of miles away.. But resting on the sunshine means resting on the Sun. That's a fact. Therefore Kṛṣṇa says, mat-sthāni sarva-bhūtāni na cāhaṁ teṣv avasthitaḥ (BG 9.4). Paraṁ brahma paraṁ dhāma pavitraṁ (BG 10.12)... Pavitram means uncontaminated. When we come to this material world, we are also spirit soul, brahman, not exactly as good as Parambrahman, Kṛṣṇa, but still, because we are part and parcel of Kṛṣṇa, we are also brahman. Pavitram. Pavitram means pure. Just like the particle of gold is also gold. If gold is pure, the particle also, pure.
So Kṛṣṇa comes to this world, we also come to this world. But we are contaminated. But Kṛṣṇa is not contaminated. The example is, just like in the prison house, there are many prisoners, but if the king, or some king's representative, minister, goes into the prison, to inspect things, how things are going on, it does not mean that the king or his minister is also a prisoner. He is not prisoner. But we, living entities, we have been entangled with these material modes of nature. But Kṛṣṇa never becomes involved in these modes of material nature. Therefore He is called pavitram paramam. Absolute pure. Bhavan, bhavan means You, Your Lordship. And purusam. Purusam, He is addressed as a person. God is never imperson. God is person. Exactly a person like you and me. And when He appeared on this planet, exactly like a human being, two hands, two legs, walking like human being, talking, behaving like human being, everything. So God is Purusam. Purusam means man. I mean to say, male. Not female. Male. Without becoming male one cannot be enjoyer. In another place it is stated that Kṛṣṇa is the Supreme Enjoyer. As soon as the word is used, enjoyer, He must be purusam, male. So that is described. Arjuna understood him. He is a purusam. Param Purusam, the Supreme Person. In another place Kṛṣṇa is described as Purusottam - the best of the males. So, purusam sasvatam. Sasvatam means eternal.
