Bhagavad-gita As It Is Lectures

Medhā means brain substance. So those who are alpa-medhasaḥ, they, means less brain substance.

Lecture on BG 2.18 -- Hyderabad, November 23, 1972:

This is the injunction of the śāstra, that in the Satya-yuga, when people were said to live for one hundred thousands of years, at that time yogic principle, meditation, was possible. And in the Tretā-yuga, the performance of big, big sacrifices was possible, because things were available, there were yājñika-brāhmaṇas. In this age, practically, there is no yājñika-brāhmaṇa who can perform yajña. No competent brāhmaṇa. Therefore performance of sacrifices is not possible. The only performance of sacrifice is this, as we are performing—Hare Kṛṣṇa festival. That is stated: yajñaiḥ saṅkīrtana-prāyair yajanti hi su-medhasaḥ (SB 11.5.32). Yajñaiḥ saṅkīrtana. In this age, Kali-yuga, no other sacrifices are..., is possible. Only sacrifice... This is sacrifice. Yajñaiḥ saṅkīrtana. Just like we are doing, in a small scale. But it can be done in larger scale. But people are not interested. People are not interested. They have lost all brain. Su-medhasaḥ, and alpa-medhasaḥ. These two words, two words are used in the śāstras. Alpa-medhasaḥ. Medhā means brain substance. So those who are alpa-medhasaḥ, they, means less brain substance. Antavat tu phalaṁ teṣāṁ tad bhavaty alpa-medhasām (BG 7.23). Alpa-medhasaḥ, less intelligent, less brain substance, they worship different demigods. Kāmais tais tair hṛta-jñānāḥ yajante anya-devatāḥ (BG 7.20). The anya-devatās are there, but who are attracted to worship other demigods? Those who are lusty. Kāmais tais tair hṛta-jñānāḥ. These are the statements in the Bhagavad-gītā. You know. Those who are lusty, and, being lusty, they have lost their senses. Hṛta-jñānāḥ. Śrīla Viśvanātha Cakravartī Ṭhākura, he says, hṛta-jñānāḥ naṣṭa-buddhayaḥ. No intelligence.
