Answer

Yes, Jainism is related to Buddhism in the sense that both are ancient Indian śramaṇa traditions that arose around the same historical period, but they are separate religions with different teachings.

Explanation

Both Jainism and Buddhism:

• began in ancient India
• emphasized non-violence, renunciation, meditation, and liberation from suffering
• challenged ritualism and worldly attachment

But they are different in important ways:

• Jainism teaches the soul is eternal and liberation comes through pure conduct, non-violence, and self-discipline.
• Buddhism does not teach an eternal soul in the same way and focuses on the Four Noble Truths and the Eightfold Path.
• Jainism has the Tirthankaras; Buddhism has the Buddha as the enlightened teacher.

Spiritual Understanding

From a Jain point of view, both traditions value moral purity, detachment, and liberation, but Jain Dharma has its own distinct path centered on ahimsa, anekantavada, and strict self-restraint.

Takeaway

So, Jainism and Buddhism are related historically and spiritually in some ways, but they are not the same religion.
