We are simply speculating in so many ways what is the ultimate cause. There are so many philosophers, but they are speculating only without any definite knowledge. So śāstra says that speculative knowledge will not be successful at any time. In the Brahma-saṁhitā it is said that panthās tu koṭi-śata-vatsara-sampragamyo vāyor athāpi manaso muni-puṅgavānām (Bs. 5.34). Manaso, by mental speculation, muni-puṅgavānām, one who speculates, he is called muni. So muni-puṅgava. Puṅgava means the most exalted muni, if he simply speculates about the Absolute Truth, how many years? Panthās tu koṭi-śata-vatsara. Just like people are now going in the outer space to find out some shelter in the moon planet, in the Mars planet, similarly, if you want to find out the Absolute Truth or the abode of the Absolute Truth... The description is there in the śāstra:
- goloka-nāmni nija-dhāmni tale ca tasya
- devī-maheśa-hari-dhāmasu teṣu teṣu
- te te prabhāva-nicayā vihitāś ca yena
- govindam ādi-puruṣaṁ tam ahaṁ bhajāmi
- (Bs. 5.43)
The topmost planet in the spiritual sky is the, called Goloka. That is Kṛṣṇa's place. Goloka-nāmni nija-dhāmni. And below this there are Vaikuṇṭha-dhāmas, unlimited number of Vaikuṇṭha-dhāmas. Goloka-nāmni nija-dhāmni tale ca tasya devī-maheśa. Devī-dhāma, this is called Devī-dhāma, this material world. And Maheśa-dhāma, the Śivaloka. And devī-mahesa, hari-dhāmasu. Hari-dhāmasu means Vaikuṇṭha. So these are the different status of dhāma. We cannot calculate, estimate even this Devī-dhāma. This is called Devī-dhāma. This material world is called Devī-dhāma. It is controlled by Devī, Goddess Durgā.
