So scientific improvement is coming, but still on the material platform. Material means gross material and subtle material. That is explained in the Bhagavad-gītā:
- bhūmir āpo 'nalo vāyuḥ
- khaṁ mano buddhir eva ca
- ahaṅkāra itīyaṁ me
- bhinnā prakṛtir aṣṭadhā
- (BG 7.4)
Earth, water, fire, air, sky, these five elements are gross material, everyone can see, gross. We can see earth, we can see water. We can see fire, air, or we can perceive the sky also. But there is subtle matter also. Mind, intelligence, ego. We cannot see the mind. We cannot see intelligence. I understand that you have got intelligence, or everyone knows we have got mind, but we cannot see. This is subtle. They are also matter, subtle matter. So the television is a machine made of gross matter, but there is possibility of making another machine of subtle matter. There is possibility. Because matter, they are also matter.
