Which reference to Indian history, who among the following is a future Buddha, yet to come to save the world?

Correct Option: Maityera (Maitreya)

Explanation:

In Buddhist tradition and iconography, Maitreya (often rendered as Maityera in some transliterations) is regarded as the future Buddha who is currently residing in the Tushita Heaven. According to Buddhist eschatology, Maitreya will appear on Earth in a future era to achieve complete enlightenment and teach the pure dharma once again when the teachings of the current Buddha, Gautama, have faded.

Let's briefly understand the other Bodhisattvas mentioned in the options:

1. Avalokiteshvara: He is the Bodhisattva who embodies the compassion of all Buddhas and is widely revered in Mahayana Buddhism.

2. Lokesvara: A form or manifestation of Avalokiteshvara, meaning "Lord of the World."

3. Padmapani: Literally meaning "Lotus Bearer," which is another popular form/manifestation of Avalokiteshvara frequently depicted in ancient Indian art (such as the Ajanta Caves).

Therefore, among the given options, Maityera is the future Buddha yet to come to save the world.
