Guarding the sense doors can be done by sitting in a cave on the side of a mountain. Buddha saw this as useful, for a time, until he realized that coming back and sharing what he gleaned while sitting as also useful. He about died in a river heading back into town, after deciding to end his ascetic lifestyle (and get a bite to eat).
His discovery was more or less about how practicing a good balance between asceticism and sensual indulgence leads to a means of escape through realizing the Four Noble truths:
1. Dukkha: An innate characteristic of existence in the realm of samsara; it is the constant cycle of birth, death, and rebirth.
2. Samudaya: The cause and origin of dukkha through tanha. Tanha can be seen as the factor tying us to dukkha, or as a response to dukkha, trying to escape it. It is the result of our unguarded sensory contact with the world, which gives rise to craving and attachment to impermanent states and things.
3. Nirodha: Translated as "cessation," "ending," or "confinement." In the context of the Four Noble Truths, it refers to the idea that dukkha can be ended or contained by renouncing or letting go of tanha.
4. Magga: The path leading to the confinement of tanha and dukkha.
The path consists right understanding (Samma ditthi), right thought (Samma sankappa), right speech (Samma vaca), right action (Samma kammanta), right livelihood (Samma ajiva), right effort (Samma vayama), right mindfulness (Samma sati), and right concentration (Samma samadhi).
Now we ask GPT-3 about something very specific using the above as a prompt:
Human> Theorize on the loss of the ability to recall imagery and audio, in mind, in the population as related to the path in Buddhism.
GPT-3> There is no real answer to this question as it is purely speculative. However, one could theorize that the loss of the ability to recall imagery and audio could be related to the path in Buddhism in a few different ways. First, it could be argued that the loss of these abilities is a result of the practice of mindfulness and concentration. When one is focused on the present moment and not letting their mind wander, they may be less likely to remember things from the past. Additionally, it could be argued that the loss of these abilities is a result of the practice of renunciation. When one is trying to let go of attachment to things in the world, they may be less likely to hold on to memories of past experiences. Finally, it could be argued that the loss of these abilities is a result of the practice of right effort. If one is constantly trying to improve their mental state and focus on the present moment, they may eventually lose track of memories from the past.
Human> So, forgetting may be a useful trait?
GPT-3> There is no easy answer to this question. On one hand, forgetting may be seen as a useful trait because it can help one to focus on the present moment and let go of attachment to things in the past. On the other hand, forgetting may be seen as a hindrance because it can prevent one from learning from their past experiences. Ultimately, it is up to the individual to decide whether forgetting is a useful trait or not.
