Padmasambhava, also known as Guru Rinpoche, is a highly revered figure in Tibetan Buddhism. He is considered to be the founder of Tibetan Buddhism and is credited with bringing the teachings of Buddhism to Tibet in the 8th century. While he shares many similarities with other Buddhist figures such as the historical Buddha and Bodhisattvas, there are also some key differences that set him apart.

One of the main differences between Padmasambhava and the historical Buddha is their origin stories. The historical Buddha, Siddhartha Gautama, was born into a royal family in India and renounced his luxurious life to seek enlightenment. On the other hand, Padmasambhava's origins are shrouded in mystery and legends. He is said to have been born from a lotus flower, hence his name which means "lotus-born." This mythical birth adds to his divine and mystical nature in Tibetan Buddhism.

Another significant difference is their teachings. The historical Buddha's teachings focus on the Four Noble Truths and the Eightfold Path, which lay out a path for individuals to achieve enlightenment. Padmasambhava, on the other hand, is known for his teachings on tantric Buddhism, which emphasizes the use of rituals, mantras, and visualizations to achieve spiritual awakening. He is also believed to have introduced the concept of Dzogchen, a form of meditation that leads to the direct realization of one's true nature.

Padmasambhava is also often depicted as a wrathful deity, which sets him apart from other Buddhist figures. This representation symbolizes his ability to overcome negative forces and obstacles on the path to enlightenment. In contrast, the historical Buddha is typically depicted in a peaceful and serene manner, representing his teachings of non-violence and compassion.

Additionally, Padmasambhava is revered as a "second Buddha" or a "fully enlightened being" in Tibetan Buddhism, while the historical Buddha is seen as the one and only Buddha. This distinction highlights Padmasambhava's importance and influence in Tibetan Buddhism.

Lastly, unlike Bodhisattvas who are seen as compassionate beings who delay their own enlightenment to help others, Padmasambhava is considered to have achieved full enlightenment and is seen as a guide and protector for others on their spiritual journey.

In conclusion, while Padmasambhava shares many similarities with other Buddhist figures, his mythical origin, emphasis on tantric teachings, wrathful depiction, and status as a "second Buddha" set him apart and make him a unique and revered figure in Tibetan Buddhism.
