In the Vedas there are many allurements for elevating oneself to higher standard of life. Just like in this life also the father says: "My dear boy, if you become highly educated, then you'll get very nice job, you'll get good salary, and you'll have nice apartment and nice wife, children."
Just like these are allurements for enticing one in this materialistic way of life, similarly, there are many allurements in the Vedic literatures. People are also, I mean to say, allured to execute such thing, that if you make such-and-such pious activities, then you get elevated to such-and-such higher planets and you get such-and-such high standard of life. These are explained there.
But Kṛṣṇa says that don't be misled by these allurement. He will explain also later on. Ā-brahma-bhuvanāl lokāḥ (BG 8.16). Just like people are trying to go to the moon planet. They are trying to go to the moon planet by some airplane or sputnik. Similarly, in the Vedic literature the travel to moon planet is also stated, that if you act in this way, then you get promotion to get your life in the moon planet. There you shall live for ten thousands of years, and you will have soma-rasa beverages, and you'll . . .
So many promises. But Kṛṣṇa says that, "Don't be allured." They are fact. They are not false statement.
