Hm. Just like if you are passing through thorns, you must be very careful. Otherwise the thorns will be stuck up with your garment, and you will be inconvenienced. It is said in the Vedas, kṣurasya dhārā niśitā duratyayā. Just like we shave with razor. Razor is very sharp. So if we can carefully handle the razor, we get our cheeks very cleansed, that business is done. But little inattention, immediately cut and there will be blood. Little inattention. That example is given. Kṣurasya dhārā niśitā duratyayā durgaṁ pathas tat kavayo vadanti. The path of salvation is very difficult. Just like we are trying to go back to home, back to Godhead, Kṛṣṇa. The path is very difficult. Kṣurasya dhārā niśitā duratyayā durgam. Durgam means very difficult to pass over. But little attention will save you. Little attention, that "I am passing through a very dangerous way, so I must be very careful." So our attention should always be how we are executing our spiritual life.
That is very simple. We observe strictly the regulative principles and chant sixteen rounds minimum. That will save us. But if we become inattentive to these principles, then there is chance of being pricked by the thorns. There are so many thorns all over. Or the same example. Kṣurasya dhārā. You shave, make your face very cleansed, but little inattention, immediately produce blood. We should be very careful.
