So Lord Kṛṣṇa says that if you want to become one of the associates in that spiritual planet, then you have to become a pure devotee. Puruṣaḥ sa paraḥ pārtha bhaktyā labhyaḥ. Bhaktyā labhyaḥ means you can attain that perfection by devotional service. And ananyayā. Ananyayā means "without any deviation." Ananyayā. What is that deviation? The deviation is that we are sometimes inclined to become a devotee for some material benefits. So here it is said that ananyayā, ananya-bhakti, without any deviation, without any material profit, you have to become a pure devotee. Then you can attain that spiritual planet.
Now, what is the nature of God? That is also... Mmmm. Yasyāntaḥsthāni bhūtāni yena sarvam idaṁ tatam. The Supreme Lord, although He's person, just like exactly a person like you and me, still, He's so, I mean to say, great that all this manifestation, spiritual or material, that is within Him. And He is also all-pervading, all-pervading by His different... Parāsya śaktir vividhaiva śrūyate (Cc. Madhya 13.65, purport), by His different energies, He's all-pervading everywhere. You can... If you develop pure Kṛṣṇa consciousness, you can see Kṛṣṇa always before you. Premāñjana-cchurita-bhakti-vilocanena (Bs. 5.38). These stages are there. So these are explained in the Śrīmad-Bhagavad-gītā. Then again Lord Kṛṣṇa explains. This is for the devotee.
