Tathāgatagarbha, also known as Buddha-nature, is a concept in Buddhism that refers to the inherent potential for enlightenment within all beings. It is often described as the "seed" or "essence" of Buddhahood that exists within all sentient beings. This concept differs from other Buddhist teachings in several ways.

Firstly, Tathāgatagarbha emphasizes the inherent goodness and potential for enlightenment within all beings. In other Buddhist teachings, such as the Four Noble Truths and the concept of anatta (non-self), the focus is on the suffering and impermanence of existence. However, Tathāgatagarbha teaches that despite the suffering and impermanence, all beings have the potential to attain enlightenment and become Buddhas.

Secondly, Tathāgatagarbha is a positive and optimistic view of human nature, in contrast to the more pessimistic views of human nature in other Buddhist teachings. The concept of anatta, or non-self, can be interpreted as the absence of any inherent self or essence within beings. However, Tathāgatagarbha teaches that there is a fundamental Buddha-nature within all beings, which is the source of their potential for enlightenment.

Another way in which Tathāgatagarbha differs from other Buddhist teachings is its emphasis on the ultimate goal of Buddhahood. While other teachings may focus on achieving enlightenment for the sake of ending suffering or attaining personal liberation, Tathāgatagarbha emphasizes the goal of becoming a Buddha for the benefit of all beings. This concept highlights the interconnectedness and interdependence of all beings, and the role of each individual in the ultimate goal of enlightenment for all.

Furthermore, Tathāgatagarbha also differs from other Buddhist teachings in its inclusion of all beings, regardless of their current state of existence. In some schools of Buddhism, only certain beings are seen as having the potential for enlightenment, such as humans or higher beings. However, Tathāgatagarbha teaches that all beings, even those in lower realms, have the potential for Buddhahood.

In summary, the concept of Tathāgatagarbha differs from other Buddhist teachings in its emphasis on the inherent potential for enlightenment within all beings, its positive view of human nature, its focus on the ultimate goal of Buddhahood, and its inclusivity of all beings. This concept serves as a reminder of the inherent goodness and potential for enlightenment within all beings, and encourages practitioners to strive towards the ultimate goal of becoming a Buddha for the benefit of all.
