Jainism vs Buddhism: did Buddhism borrow from Jainism? I've come across Jainism through looking for texts on Buddhism and I've found there seems a considerable amount of overlap. Did Siddhartha Gautama encounter or study under any Jainist teachers? It seems Jainism predates Buddhism by a lot so were these concepts also predating Siddhartha too?
Jainism: The ultimate goal of Jainism is the liberation of the self (jiva) from rebirth, which is attained through the elimination of accumulated karma (the consequences of previous actions). This occurs through both the disciplined cultivation of knowledge and control of bodily passions. When the passions have been utterly conquered and all karma has been removed, one becomes a Jina (&quot;conqueror&quot;), and is no longer subject to rebirth.
These principles include non-violence in all parts of life (verbal, physical, and mental), speaking truth, sexual monogamy, and the detachment from material things. As part of the disciplined and non-violent lifestyle, Jains typically are strict vegetarians and often adhere to a quite arduous practice of non-violence, which restricts the sorts of occupations they may follow (no farming, for instance, since insects are inadvertently harmed in plowing). Jainism's ethical system is based on the idea that right faith, knowledge, and conduct must be cultivated simultaneously.
Like comparing rules of monks and even the five precepts are identical from what I found.
The five precepts and five vows are identical from what I saw.
This is a list of comparisons and contrasts.
Sounds a whole lot like Buddhism to me! Does anyone know about the Jainism/Buddhism comparison?
There are very strong similarities between Buddhism and Jainism but there are also a number of major differences as well. 

It is very true that Buddhism and Jainism use a lot of very similar terminology, but these are mostly terms that were floating around among the Shramanas (ascetics) for some time. Karma, rebirth, the goal as escape from rebirth. etc... were ideas that were not unique to either Buddhism or Jainism but were held by many different groups of ascetics. For example, the Ajivaka school taught very similar things on these points as well. The general terminology of rebirth and karma was a general part of the Indian ascetic tradition as a whole, rather than just Jainism.

However, when you look at how these concepts are actually understood in Jainism and Buddhism you find there are major differences. It seems that the Buddha borrowed existing terminology but gave it radically new meanings. The best example I can think of is in the Buddha's understanding of Karma compared with the Jain understanding of Karma.

The Jains (according to my knowledge) think of Karma as being some sort of subtle substance that sticks to one's Jiva, or soul. The Jiva is bound to a physical body, and as a result becomes loaded up with Karma, which weights it down and interferes with one's spiritual understanding. When one dies the kind of Karma stuck to your Jiva determines your rebirth. Through ethical living you can stop more karma from being accumulated and through ascetic practice you can 'burn up' the karma stuck to your soul, and if you can get rid of all of it, you become enlightened, and will then be reborn into a special heaven without a physical body where you will be just a Jiva and will stay that way forever.

The Buddha rejected the idea that Karma is any sort of substance and rejected any kind of soul or self as well. To the Buddha, Karma refers to an action with mental intention. The Buddha said this in many places, saying "Intention, I tell you, is kamma. Intending, one does kamma by way of body, speech, &amp; intellect." and in several Suttas the Buddha spoke out against the Nigantha's (that's what the Jains were called at that time) understanding of Karma.
