Here, just like when we become intoxicated, we become addicted to so many sinful actions, it is soma-pāḥ. When we drink soma-rasa, it is just the opposite. We become freed from all sinful reaction. So that soma-pāḥ is recommended here also. So either they try to go to other planets, or they manufacture here soma-pāḥ, soma-rasa. Of course, at the present moment we have no such facility. But from Bhagavad-gītā it is understood that there was a method.
Anyway, the process is mentioned, described, in the Vedic literature, trai-vidyā. Trai-vidyā means Vedas. There are three kinds of knowledge in the Vedas, trai-vidyā: karma-kāṇḍa, upāsanā-kāṇḍa and jñāna-kāṇḍa. Karma-kāṇḍa means this how we can adjust material happiness or material living very nice. That is called karma-kāṇḍa. And then upāsanā-kāṇḍa. Upāsanā-kāṇḍa means how to worship the Supreme Lord or the demigod or different types of . . . there are demigods. The demigods are living beings like us, but they are very powerful. So that upāsanā-kāṇḍa, worship of different demigods, is also mentioned there in the Vedas. That is called upāsanā-kāṇḍa. And jñāna-kāṇḍa. Jñāna-kāṇḍa means knowledge, philosophical.
So therefore Vedas is known as trai-vidyā, trayī. Trayī means three kinds of knowledge there are. So the persons who are more or less materialist—they are not transcendentalist—they take shelter of this Vedic trai-vidyā, three kinds of knowledge. And to prepare themself to be transferred in other planets they become freed from all sinful reaction.
