How is the life and teachings of Gautam Buddha or
Vardhmana Mahavira relating it with SDG
Answers
Answer:
From where I see it, there is no difference between the two. They both were enlightened Shramana masters. Jina - The Mahavira was the last and 24th Tirthankara (Ford-maker) of Shramana tradition and Gautama - The Buddha its brightest star ever because of whom this tradition is now well known across the globe.
However, this answer will not go well with the followers of Jainism and with those of Buddhism as each of the followers regard their own master to be completely enlightened and the other as a heretic preacher.
Thus, to justify my answer, I will try and explain in detail in below two sections. Please pardon me for a long answer, but it's important so that I may not be accused of Mithyatya or Wrong-Insight by either of the two groups for comparing two assumed unequal as equal.
In the first section, I will discuss what general believers of Jainism and Buddhism believe about the masters of the opposite creed and the probable reasons for the same, and then explain why these assumptions are wrong.
In the second section, I will explain whether it's possible for two completely enlightened masters to co-exist as per Shramana school - the mother of both traditions.
1st Section:
What do Buddhist annals claim of Jina?
Jina, is referred to as one of the six great contemporaries of Buddha. He is often associated with one of the extreme wings of various Shramana schools that existed during the time of Buddha and is thus claimed as faulty.

Nothing could be further than truth as Jina unequivocally denounced such practices.
Further, a lot of Buddhist annals associate a lot of philosophies with Jina that were never a part of His teachings.
Say for eg, Majjhima Nikaya 1, Saccaka, has been shown to be a Jain monk - the follower of ‘Nigan.tha’. This is not true, for neither his philosophy is in tune with the message of Jina, nor is his description or lifestyle in tune with that of Jain monks. Below are a few examples.
- Saccaka claims his material body, feelings, perceptions, etc to be his true self. This is not so as per Jainism. Body and bodily properties made of matter are referred to as "Pudgal" (matter) which is one of the six fundamental substances (Dravya) of the universe. The concept of self in Jainism is referred to as "Jiva". This is another of the six fundamental substances that constitute the universe. It means "The Being" or "Soul" which is caught in the cycle of transmigration till it achieves Moksha. No follower of Jainism would ever equate pudgal (matter) that the body or mind is made off with Jiva or soul.
