The living entity in this way wandering in different species of life in different planetary platform, and therefore this is very disgusting, so if one is fortunate, then he comes in contact with a devotee. This Kṛṣṇa consciousness movement is meant for giving this opportunity to everyone. We are opening centers all over the world, inviting people to "Come in our place. Understand the philosophy. We have got so many books. And try to save yourself from this botheration of repetition of birth and death." In order to execute to this business, apparently there is little difficulty. Just like we prescribe to our members, "No intoxication." So no intoxication... One who is habituated to drink, to smoke, to drink coffee, tea, etc., he feels some discomfort. Similarly, we say, "No meat-eating." So those who are meat-eaters, they will find little difficulty to give up this habit. Similarly, we say, "No illicit sex," but one who is habituated for this illicit sex life, he feels some difficulty. So there are so many things. In the beginning it appears to be little difficult. Actually it is not difficult, but because we are habituated, we feel difficulty. So if you are actually anxious and serious to stop this repetition of birth and death, then we must take to Kṛṣṇa consciousness, because without Kṛṣṇa consciousness nobody can stop the repetition of birth and death. Therefore Kṛṣṇa advises in this verse that "Accept this little difficulty." Actually there is no difficulty, but because we are practiced, in the beginning we find little difficulty. Therefore here Kṛṣṇa says, yaṁ hi na vyathayanty ete: "All these so-called difficulties, if they do not bother or give some pain to a person..." Yam... All these difficulties... Just like I am feeling difficulty. I am habituated to smoke. Now I am forbidden, "Not to smoke." So I am feeling difficulty. So therefore Kṛṣṇa said, "Although it is not difficulty, but although one feels difficulty—still he sticks to the principle—then he becomes fit for going back to home, back to Godhead." So indriyāṇi pramāthīni, in the Bhagavad-gītā you'll find. Our senses are very strong, like mad snakes. There is some statement in Vedic literature, indriya-kāla-sarpa-paṭalī. Indriya, the senses, are just like dreadful snakes. But there is a means to subdue the snake. It is said, indriya-kāla-sarpa-paṭalī protkhāta-daṁṣṭrāyate, means the snake may be very dangerous, but somehow or other, if you take out its poison teeth, then it is no more dangerous." The snake is dangerous on account of the poison teeth. So if, somehow or other, the poison teeth extricated, then the snake is no more dangerous. So our strong senses, snakelike senses, can be bereft of the poison teeth by accepting Kṛṣṇa consciousness.
So the simple method offered by Śrī Caitanya Mahāprabhu is this chanting Hare Kṛṣṇa mantra. He says personally, ceto-darpaṇa-mārjanaṁ bhava-mahā-dāvāgni-nirvāpaṇam (CC Antya 20.12), means "By chanting Hare Kṛṣṇa mantra your heart will be cleansed, and as soon as your heart is cleansed, you can feel everything in its proper order." So when the heart is cleansed we can understand our real position and how we are suffering and how to take steps against this suffering. This is called bhava-mahā-dāvāgni-nirvāpaṇam, extinguishing the blazing fire of material existence. In this verse it is mentioned again, dhīra. Dhīra means very sober. In the beginning Kṛṣṇa said, dhīras tatra na muhyati (BG 2.13). Dhīra means one who is sober. He is not bewildered. So dhīra means that although there is cause of disturbance, one is not disturbed. Although there is cigarette, but I should promise, "I shall not smoke." Although there is facility for illicit sex, I'll not do it. That is called dhīra. Dhīra means the cause of agitation or disturbance is present there, but one is not disturbed. So in order to advance in spiritual life we have to become dhīra. And that is said here, sama-duḥkha-sukhaṁ dhīram. As soon as one become dhīra, sober, these so-called material pains and pleasure does not disturb me (him). Then he is fit for becoming immortal. Everyone is immortal, but he is fallen in such material condition that he thinks himself as mortal. Because I am spirit soul, therefore the Vedic injunction that feel:(?) ahaṁ brahmāsmi, so 'ham, means "I am as good as the Supreme Being," means "He is eternal; I am also eternal. He is also living being; I am also living being." That means qualitatively we are one, God and me. But quantitatively, He is great; we are small.
So we have to realize this, that we can become eternal, immortal, all qualified like God, if we get out of these material clutches. And for this, we have to become dhīra. Dhīra means, I have already explained, not to be disturbed, even the cause of disturbance is there. So that is the qualification of becoming immortal. So little tolerance of the sensation... Just like there is some sensation. If you have got some itches and you are feeling that "I should itch," but if you stop itching, this will be cured, and if you go on itching, it will increase. So itching... Anyone who has got some experience of itching... Itching is very pleasing at the time of itching, but next time it is not very pleasing. It has created so many disturbing condition. Therefore śāstra says that we should try to control the itching of our senses. Then he is dhīra. And as soon as you become dhīra, you are the first-class candidate for going back to home, back to Godhead. So there is method; there is practice; there is process. If you like, you can adopt them—actually there is no difficulty—and solve all the problems of your life. This is Kṛṣṇa consciousness movement. Try to understand and adopt it.
