The difficulty is that they do not know what is siddhi. At the present moment, people are so ignorant that they do not know what is siddhi. The major problem of life, that is unsolved. Everyone is trying to make a solution of some temporary difficulties—politically, socially, economically—but real solution, as it is stated in the Bhagavad-gītā, janma-mṛtyu-jarā-vyādhi-duḥkha-doṣānudarśanam . . . (BG 13.9). Janma, birth, mṛtyu, death, and jarā, old age, and vyādhi, disease—to get out of this entanglement.
Duḥkha-doṣānudarśanam. This is our real miserable condition of life. We have to die, we have to take birth again, and again we have to become old, and there will be disease. Between birth and death . . . birth is very miserable. To remain in the womb of the mother in a packed-up stage within a bag, and . . . that is miserable. Biting, the worms biting tender skin. We have forgotten, but these were the miseries for birth. In suffocated condition . . . but we have forgotten. So forgetfulness is not solution. Closing the eyes before the enemies is no solution. Daivī hy eṣā guṇamayī mama māyā duratyayā (BG 7.14).
