SB 2.3.6

There are different modes of worship for different persons desiring success in particular subjects. The conditioned soul living within the purview of the material world cannot be an expert in every type of materially enjoyable asset, but one can have considerable influence over a particular matter by worshiping a particular demigod, as mentioned above. Rāvaṇa was made a very powerful man by worshiping Lord Śiva, and he used to offer severed heads to please Lord Śiva. He became so powerful by the grace of Lord Śiva that all the demigods were afraid of him, until he at last challenged the Personality of Godhead Śrī Rāmacandra and thus ruined himself. In other words, all such persons who aspire after gaining some or all of the material objects of enjoyment, or the gross materialistic persons, are on the whole less intelligent, as confirmed in the Bhagavad-gītā (7.20) . It is said there that those who are bereft of all good sense, or those whose intelligence is withdrawn by the deluding energy of māyā, aspire to achieve all sorts of material enjoyment in life by pleasing the various demigods, or by advancing in material civilization under the heading of scientific progress. The real problem of life in the material world is to solve the question of birth, death, old age and disease. No one wants to change his birthright, no one wants to meet death, no one wants to be old or invalid, and no one wants diseases. But these problems are solved neither by the grace of any demigod nor by the so-called advancement of material science. In the Bhagavad-gītā, as well as in the Śrīmad-Bhāgavatam, such less intelligent persons have been described as devoid of all good sense. Śukadeva Gosvāmī said that out of the 8,400,000 species of living entities, the human form of life is rare and valuable, and out of those rare human beings those who are conscious of the material problems are rarer still, and the still more rare persons are those who are conscious of the value of the Śrīmad-Bhāgavatam, which contains the messages of the Lord and His pure devotees. Death is inevitable for everyone, intelligent or foolish. But Parīkṣit Mahārāja has been addressed by the Gosvāmī as the manīṣī, or the man of highly developed mind, because at the time of death he left all material enjoyment and completely surrendered unto the lotus feet of the Lord by hearing His messages from the right person, Śukadeva Gosvāmī. But aspirations for material enjoyment by endeavoring persons are condemned. Such aspirations are something like the intoxication of the degraded human society. Intelligent persons should try to avoid these aspirations and seek instead the permanent life by returning home, back to Godhead.
