Shrila Prabhupada says the following in the lecture delivered at LA on June 1st, 1972 on SB 2.3.15 about the Holy Name of the Lord.

“There are very nice verses in Bhāgavatam. Nivṛtta-tarṣair upagīyamānāt. This chanting of the holy name of Kṛṣṇa, or God, is possible by a person who is disgusted with all these material activities. They can actually chant. That means mukta-puruṣa, liberated soul. It is… The chanting of Hare Kṛṣṇa mantra is the business of liberated soul, not for the conditioned soul. But even in our conditioned life we chant, we become gradually purified.

Therefore it is recommended that everyone should chant. Never mind, nama oṁ apavitraḥ pavitro vā yaḥ smaret puṇḍarīkākṣam. Anyone who remembers the Puṇḍarīkākṣa… By chanting, you’ll remember. So nivṛtta-tarṣair upagīyamānād bhavauṣadhi. It is the medicine for our this bhava-roga, repeated birth and death. Such a nice thing. Nivṛtta-tarṣair upagīyamānād bhavauṣadhi chrotra-mano-‘bhirāmāt. Not only it is medicine… Medicine is always bitter. But it is not bitter. Mano ‘bhirāmāt: it is very pleasing to the mind, to the senses. Otherwise, how we become ecstatic in chanting unless it is pleasing? It is medicine, but pleasing medicine. Other medicines, they are very bitter. If you practice yoga, oh, you have to take so much labor. And that, you do not know whether you’ll be successful or not, haṭha-yoga. And if you take to jñāna, that also requires much education, much understanding of philosophy.

So they actually, although they are medicine, but they are bitter medicine. Not very palatable. Neither everyone can take it. A child cannot become a jñānī. A child cannot become a yogī. But a child can become a bhakta. Therefore this is the easiest process. Pleasing. Everyone is pleased to execute this process. Nivṛtta-tarṣair upagīyamānād bhavauṣadhi chrotra-mano-‘bhirāmāt [SB 10.1.4]. Mano-‘bhirāmāt. Even for ordinary men who wants to hear about conjugal love… They read therefore so many novel, fiction, dramas. What is that? The love affairs between one young man, one young girl. But that is also there, Kṛṣṇa, Rādhā-Kṛṣṇa. In that sense also, it is pleasing, even to the ordinary man.
So, mano ‘bhirāmāt, it is very pleasing.”

A brief on what Prabhupada is saying above:
1] Holy Name is a pleasing medicine – manobhiramat
2] It is chanted actually by liberated souls, but conditioned soul can also take benefit.
3] Holy Name can be taken by anyone regardless of prior background.
4] Holy Name consists of all pastimes – conjugal love – who doesn’t want to hear between the love of a boy and girl? So, it’s pleasing to the ordinary man also!

So many pleasing effects of taking a medicine. Obviously, we all take medicines to cure ourselves, but often they are bitter.
Holy Name is the tastiest medicine. Therefore, it is said – madhuram madhurebhyo ‘pi – it is the sweetest among all sweet things.

King Kulashekhara says that in this material world, there is no use of taking any other medicine. The body is going to meet its desired end. So, the best thing to take is the elixir of Krishna’s Holy Name. That can give us eternal life.
idaṁ śarīraṁ pariṇāma-peśalaṁ
pataty avaśyaṁ śata-sandhi-jarjaram
kim auṣadhaṁ pṛcchasi mūḍha durmate
nirāmayaṁ kṛṣṇa-rasāyanaṁ piba
“This body’s beauty is fleeting, and at last the body must succumb to death after its hundreds of joints have stiffened with old age. So why, bewildered fool, are you asking for medication? Just take the Kṛṣṇa elixir, the one cure that never fails.”

Then he says that surprisingly, people are leaving this nectar of Holy Name and instead engaging in drinking poison.

Sanatana Goswami also mentions Holy Name as the topmost nectar – paramam amrtam ekam jivanam bhusanam me.

We must earnestly pray every single day so that Krishna enables us to taste the nectar of the Holy Name for which we are always anxious.
