Yoda was not a hermit in the sense of complete detachment from what was happening. While on Dagobah, he used force to train other Jedi: Ezra Bridger, Keinan Jarrus. Communicated with the spirit of Qui-Gon Jinn. In addition, he must have felt that the bright side had not yet dried up in Vader. But Vader and Sidious Yoda on Dagobah did not feel. There, on the planet itself, living things create the background of natural strength. Otherwise the planet would have been destroyed. In addition, Vader and Sidious believed Yoda was dead. Vader tells Ahsoka in the last episode of Rebels Season 2 that the Emperor will spare you if you tell him where to find the last Jedi. He seems to be referring to ObiWan, because when they meet later on the Death Star, Vader will say, ObiWan was waiting for you. Therefore, it cannot be said that Yoda was in isolation, he was in a stream of power. The bright side of the force as a reaction to imbalance after the destruction of the Jedi began to actively act. And later she brought Luke to Dagoba.
If you remember, in episode 3 at the end, Yoda and Obi-Wan talked about Obi-Wan's teacher, Quigon Jin. He managed to open the way to immortality through strength. Apparently Yoda and Obi-Wan, being both in exile, learned exactly this.
Quygon Jin was an advocate of manpower, a doctrine that did not deny all emotion as the Jedi did. The path of manpower taught that you need to experience good emotions and keep away from evil ones (if in a simple way). And also that you need not look into the future, but focus on the present (remember the dialogue between Obi-Wan and Quygon in episode 1). It is assumed for this reason that the Jedi did not notice what was happening in front of their noses, because they spent little time on the present, but often thought about the future and about the prophecy. And as a result, they misinterpreted him.
Well, we must not forget that Yoda was already old, he was 900 years old and he was not able to fight. Unlike Palpatine, he did not strive for bodily immortality.
Well, this was a necessary measure, since he was hiding from Darth Vader and Palpatine, and he could not cope with them alone.

Master Yoda is one of the central characters in the Star Wars cinematic universe. He is the oldest Jedi and a member of the Intergalactic Council of Jedi, space monks with laser swords who must maintain the balance of the dark and light sides of the Force.
Yoda has been in two exiles in his life. The first time he went into exile was to gain strength and experience while training. The second time it turned out that all his strength, wisdom, knowledge were not enough to feel that a terrible conspiracy of dark forces was taking place right next to him. He did not see that Chancellor Palpatine was actually a villain who was trying to transform the Republic into an Empire, to seize power in it. At the same time, Palpatine was also the Lord of the Sith.
Yoda realized that he had not coped with his task and lost in the battle with Palpatine, and the forces of evil staged the genocide of all Jedi. He had to flee into exile, hide as punishment for his own lack of understanding, in order to wait for the right moment to retaliate. He went to the planet Dagobar, where he sat in a cave for 22 years and did a hell of a lot. And then he trained Luke Skywalker to save the galaxy.
In short, he decided that he was to blame for these mistakes, and decided to punish himself.
He, as one of the most powerful followers of the Light, had to hide from an even more powerful follower of Darkness. He knew there was nothing he could do after being defeated by the Emperor, but he foresaw that he could play a role in the future and overthrow Palpatine by proxy. And so it happened in the end. He managed to disguise himself on a planet where there is a lot of life and it is not easy to find him. In addition, he chose a place of residence near the concentration of the Dark Force, which also drowned out his own Light.
I do not pretend to be the ultimate truth, and even more so I don’t know exactly how asceticism is considered in Buddhism, but I can see that in the case of Jediism, Yoda’s asceticism can be interpreted as leaving the world to merge with the Force.
It has already been correctly noted that this happened after the destruction of the Jedi Order and Palpatine's victory on all fronts, and Yoda himself in "Revenge of the Sith" says: "I must go into exile. I suffered a fiasco." However, this seems more likely a reason, but clearly not a reason. I think that after the defeat, Yoda realized that it was necessary to listen to the Force, to understand what purpose he and all the Jedi have and which path to follow in order to fulfill their purpose. Asceticism in this case becomes a way of solitude and conscious merging with the Force.
I may be wrong, but it seems to me that the ability of Yoda and Obi-Wan (who, by the way, also became a hermit) to appear in the form of Force ghosts is connected with this. Then, of course, the question arises of how Anakin Skywalker was able to manifest in the Force after death (unless the life of Darth Vader can also be called a kind of austerity), but this is a separate topic for discussion.
This is such a practice, and the theory is presented in Buddhism, for example, in Tinley's book "Mind and Emptiness" - emptiness must be imagined within oneself, around oneself, this is a form of meditation. And Master Yoda, moving away, wants not only people, but also thoughts not to be distracted. This zeroing is a purification, a complete emptying. If a person goes into asceticism, the goal is zeroing before a new round of trials, so that development proceeds in a spiral: you make a circle, then zero, and you go in a circle, but not the same, but one step higher. A person grows wiser over the years, rises up.
It is not necessary to leave for a month or a year. You can go for at least 15 minutes - on the plane, in the car. The 14th Dalai Lama left for five years, I have many acquaintances who regularly go into asceticism. In Russia there was Geshe Jampa Tinley Wangchen, he was in asceticism in Buryatia, in Novosibirsk.
I had a record of asceticism for a week. I was in the Indian city of Darmsala, went to visit the Dalai Lama, and practiced at the Vatican for a couple of days, went to visit the Pope, there in the mountains to the monastery where he practices himself.
Of course, I advise everyone to study this topic deeper. There are various books, lectures of the Dalai Lama, such as: "The Art of Being Happy", "The Art of Being Happy at Work.
What the commentator said below.
Defeat Yoda suffered as the head of the Jedi Order and as a champion of the light side. The enemies of their Sith adapted, learned to hide behind masks, but the Order did not even know. Palpatine outwitted Yoda, outwitted and condemned the entire Order to death - many heroes fell then, many good people, and the galaxy forgot about justice and love, and hatred reigned in her heart, and Yoda could not do anything about it. Master Yoda let down everyone he knew, lost everything he had fought for for centuries, lost his most important battle, and had to flee.
And Yoda spent years alone, trying to figure out what he did wrong and how to bring new hope to the galaxy.
The depression that was simple, it seems to me.
For with their bestial attitude they profited the mighty Jedi (and he left the dark side.), they did not understand the prophecy, they did not notice the conspiracy, they turned out to be incapacitated, as a Jedi order.
