God realization means spiritual realization. So Ṛṣabhadeva says, tapo divyaṁ putrakā yena sattvaṁ śuddhyed (SB 5.5.1): by purification of your existentional condition you enjoy brahma-saukhyam. After all, we are searching after happiness, pleasure. So on account of our impure existential condition, our so-called happiness is temporary. Brahma-saukhyam means, here again, yena sattvaṁ śuddhyed, when your existence is purified. Now we have got impure existence, this material body. When we get our spiritual body, that is called purified.
So Ṛṣabhadeva says, sattvaṁ yasmād brahma-saukhyam anantam. As soon as you get your spiritual body, then there is unlimited happiness. We are, after all . . . in the Vedānta-sūtra it is said that the living entity or God, both of them are for enjoying life, blissful life. Just like when you are diseased, you have got some fever, so you cannot enjoy life. Similarly, in this diseased condition of material existence we, actually, we cannot enjoy life. Therefore, if we purify our existentional condition by tapasya, then we come into our spiritual existence and we can enjoy our life eternally. (break) . . . therefore, that when we have got this human form of life, we shall not waste it simply for sense gratification like the dogs and hog. We should practice tapasya, restrain, and then we purify our existence, and we are situated in a position wherein we can enjoy blissful life forever.
Now the process is prescribed how to execute this tapasya life. Ṛṣabhadeva says, mahat-sevāṁ dvāram āhur vimuktes: to get liberation, liberated from this entanglement of material life, one has to serve mahat, great saintly person. (break) Mahat-sevāṁ dvāram āhur vimukteḥ (SB 5.5.2). Vimukteḥ means for liberation. If you want to get liberation from this material bondage, repetition of birth, death, old age and disease . . . and not only that; so long we live, there are so many miserable conditions of life. This is called material existence. If we want to get out of this entanglement, then we must take to the service of great saintly personalities. So that is the way for liberation, mahat-sevāṁ dvāram āhur vimuktes tamo-dvāraṁ yoṣitāṁ saṅgi-saṅgam.
There are two; just like we are in the crossroad, which way we shall go? That can be understood in this human form of life. This human form of life, we have come to this point by evolution. Now we are on the . . . just on the crossroad, whether we shall go this way or that way. If we want to be free from the entanglement of material misery, then here it is recommended, mahat-sevām: we must render service to the holy, saintly person. And if you want to go deeper and deeper in the darkest region of existence, then we should turn our face for sense gratification.
