Devotee: Verses 27 and 28. "Shutting out all external sense objects, keeping the eyes and vision concentrated between the two eyebrows, suspending the inward and outward breaths within the nostrils—thus controlling the mind, senses and intelligence, the transcendentalist becomes free from desire, fear and anger. One who is always in this state is certainly liberated (Bg. 5.27-28)."
Prabhupāda: Now here is a hint of the yoga practice, shutting out the external sense objects. This is another process. But the bhakti-yoga process is automatically yoga process. Here it is said, "shutting out all external sense objects." Sense object, what is that sense object? Just like I want to see some beautiful woman or beautiful man. I want to smell some nice flower or scent. The flower is the sense object, woman is the sense object. There are so many sense objects. We have got five senses and there are five objects also. Otherwise what is the use of sense? Now this yoga practice is to withdraw the senses from the sense object. But the bhakti-yoga process is that if I do not like to see artificially the beauty of woman or man, if I try to see the beauty of Kṛṣṇa, naturally my, this propensity of seeing beautiful man or woman becomes extinguished. You do not require to shut your eyes. There are so many beautiful girls sitting. I do not require to shut my eyes. If my mind is concentrated on the beauty of Kṛṣṇa I can see these beautiful girls as Kṛṣṇa's gopīs. That is another vision. So artificially if I close my eyes and if some beautiful girl is in my imagination even after closing my eyes here, what is the use of closing your eyes?
So by force you cannot control the senses. That is not... This is... There are many instances. Even great yogis they have failed. This is artificial way of controlling the senses. The real sense control is that you purify your sense in the activities of Kṛṣṇa consciousness. That is real sense control. Hṛṣīkeṇa hṛṣīkeśa-sevanaṁ bhaktir ucyate (CC Madhya 19.170). Hṛṣīka means senses and hṛṣīkeśa means Kṛṣṇa.
