Hṛt-tāpa. There is a hṛt-tāpa. Hṛt means heart, and tāpa means . . . tāpa means, real meaning is temperature, or temperature-rooted. Just like agni-tāpa. Agni. Agni means fire, and tāpa, it has got temperature. So to a certain degree you can tolerate. But when the degree . . . just like in India we have got temperature in summer season 120 degree. Here, just like in your country, the temperature is less. In other country . . . the temperature in, I mean, the Middle East, the temperature is 135 degree, Arabian countries.
So there are three tāpas, three kinds of miserable condition, this material world. That also can be taken tāpa. Tāpa means suffering. Excessive heat and cold, that is called tāpa. So hṛt-tāpopaśamāni ca. The teachings of Bhagavad-gītā . . . We are suffering always within the heart. As Narottama dāsa Ṭhākura says, that viṣaya viṣānale, divā-niśi hiyā jvale (from Gītāvalī). Viṣaya. Viṣaya means this material enjoyment. it is just like poison. The more we are entangled in material enjoyment . . . there is no enjoyment, it is suffering. But we are taking suffering as enjoyment. Just like in this winter season we cover ourself very nicely with gloves, with overcoat. It is simply counteracting the suffering. But a man who has got a nice overcoat and gloves, he is thinking he is enjoying. This is māyā. He forgets that he is simply trying to counteract the suffering. Actually, he is suffering. But having a nice coat or nice place, he is thinking that he is enjoying. That is foolishness. That is called māyā. There is no enjoyment in this material world. Simply we are trying to counteract the suffering. This counteraction of suffering we are accepting as enjoyment.
So this material world means you must suffer. That is the position of the material world. Otherwise, why you have come to material world? Just like in the prison life, how you can expect enjoyment there? But a man . . . suppose a big politician is put into the jail and he is given a very nice, comfortable bungalow and everything, but he is in the jail. But he is thinking that, "I am enjoying." He forgets that he is in the jail. He is in the jail. That is called ignorance, māyā. He is suffering and he is accepting. Just like the pig: he is eating stool, but he is thinking he is enjoying. This is going on.
So hṛt-tāpa. In this, I mean to say, ocean of suffering, viṣaya viṣānale, divā-niśi, the more we want to enjoy, the more sufferings enter. More suffering. You can understand: Just now we got this car, horseless car. But now there is a problem. They are thinking, "If there is no petrol available, then what will happen?" So this is material existence. Viṣaya viṣānale, divā-niśi . . . anxiety. That anxiety is suffering, "What will happen? What will happen?" That is material existence. Sadā samudvigna-dhiyā. Always full of anxieties. This is material life.
So Narottama dāsa Ṭhākura says that viṣaya viṣānale, divā-niśi hiyā jvale: "The heart is burning on account of this material existence." Tori bare nā kainu upāya (Prārthanā, Song 4): "But I did not try to find out the means by which I can get out of this." Golokera prema-dhana, hari-nāma-saṅkīrtana, rati nā janmila kena tāya. The medicine is this Hari, Kṛṣṇa: Kṛṣṇa's teachings, Kṛṣṇa's name, Kṛṣṇa's glorification. That is the real medicine. But we have no attraction for these things. We are simply trying to counteract the suffering, and we are accepting this counteraction as enjoying. Bhagavad-gītā. Haranti smarataś cittam (SB 1.15.27).
So actually if we want to enjoy life, then we should take the instruction of Bhagavad-gītā, Kṛṣṇa. We shall chant Hare Kṛṣṇa mantra. That will give us relief from the blazing fire. Saṁsāra-dāvānala-līḍha-loka-trāṇāya kāruṇya-ghanāghanatvam. This is the only way. Otherwise . . . so when Arjuna was too much perturbed by absence of Kṛṣṇa, he was simply remembering the instruction of Kṛṣṇa which he received in the Battle of Kurukṣetra.
