Indian guest: We try to heat the home in the winter season, and it is a hard time heating a home. We don't have energy, run short of energy. But summer comes and nature heats it up that we are just too hot. So the nature's energy supply is just unlimited. Science cannot even imagine a small fragment.
Prabhupāda: Our science is stated in the Vedas, yasmin vijñāte sarvam evaṁ vijñātaṁ bhavanti. Just try to understand Kṛṣṇa, and everything will be understood. So try to understand one, Kṛṣṇa, and then you understand everything. Yasmin vijñāte sarvam evaṁ vijñātaṁ bhavanti. (break) ...philosophy is, it is said, that bhaktim... śreya-sṛtiṁ bhaktim... śreya-sṛtiṁ bhaktim upasya, ye kliśyanti kevala-bodha-labdhaye. Kevala-bodha means just trying to understand this, that, this, that, this, that, this, that. In this way they are wasting time and giving up devotional service to the Lord. So what is the result? Bhaktim udapasya te vibho kliśyanti ye kevala-bodha-labdhaye. Kevala-bodha. The duration of life is very short, and he is gathering knowledge by going to the moon. In this way he is wasting his time. So the result is that waste of time. That is their gain and nothing more. Just see that these people instead of teaching Kṛṣṇa consciousness, they wanted to study, go to the moon planet to understand. The result is, their only result is, that they have labored so much, and that is their gain, nothing else. What other thing they have made. Teṣāṁ kleśala evāvaśiṣyate nānyad yathā sthula-tuṣāvaghāṭīnām. Just like you beat the skin of rice paddy. You will not get rice. Simply your labor, "Gad, gad, gad, gad," that will be your gain. So their only gain is that they have learned that in the moon there is dust like here, that's all. This is their... (laughs) As if we are very much eager to know that there is also dust in the moon. (laughs) And they bluff people selling ticket for going to moon planet.
