Leaders should think over it, that "What we are producing, in spite of so many educational institution?" That is hinted here, that because you are worshiping avidyā . . . that is not knowledge. Bhaktivinoda Ṭhākura has sung very nicely: jaḍa-vidyā saba māyāra vaibhava. Jaḍa-vidyā. Jaḍa-vidyā means this material education. He says they are expansion of this māyā. Jaḍa vidyā. Jaḍa vidyā sa māyāra vaibhava, tomāra bhajane bādhā. The more we shall advance in this material education, the more we will be hampered to understand what is God. And at last, we shall declare, "God is dead. I am God. You are God," this, all this nonsense.
That is hinted here: andhaṁ tamaḥ. Andham means darkness. There are two kinds of darkness. If you remain in ignorance, that is also darkness, and if you remain actually in darkness, where there is no sunlight, there is no electric light, that is also darkness. So avidyām upāsate. Another, tato bhūya iva te tamo ya u vidyāyāṁ ratāḥ (ISO 9).
So these materialists, they are certainly being pushed in the darkness. But there is another class, who are so-called philosopher, mental speculators, religionists, yogīs, they are going still more in the darkness, because they are defying Kṛṣṇa. They are posed as if culturing spiritual knowledge, but because they have no information of Kṛṣṇa, or God, their advancement of education is also more dangerous. More dangerous, because they are misleading people.
