Passage: English Dominican mysticism in the late medieval period differed from European strands of it in that, whereas European Dominican mysticism tended to concentrate on ecstatic experiences of union with the divine, English Dominican mysticism's ultimate focus was on a crucial dynamic in one's personal relationship with God. This was an essential moral imitation of the Savior as an ideal for religious change, and as the means for reformation of humanity's nature as an image of divinity. This type of mysticism carried with it four elements. First, spiritually it emulated the moral essence of Christ's life. Second, there was a connection linking moral emulation of Christ's life and humanity's disposition as images of the divine. Third, English Dominican mysticism focused on an embodied spirituality with a structured love of fellow men at its center. Finally, the supreme aspiration of this mysticism was either an ethical or an actual union with God.
What did European mysticism and English mysticism both concentrate on?

Passage: The concept of legal certainty is recognised one of the general principles of European Union law by the European Court of Justice since the 1960s. It is an important general principle of international law and public law, which predates European Union law. As a general principle in European Union law it means that the law must be certain, in that it is clear and precise, and its legal implications foreseeable, specially when applied to financial obligations. The adoption of laws which will have legal effect in the European Union must have a proper legal basis. Legislation in member states which implements European Union law must be worded so that it is clearly understandable by those who are subject to the law. In European Union law the general principle of legal certainty prohibits Ex post facto laws, i.e. laws should not take effect before they are published. The doctrine of legitimate expectation, which has its roots in the principles of legal certainty and good faith, is also a central element of the general principle of legal certainty in European Union law. The legitimate expectation doctrine holds that and that "those who act in good faith on the basis of law as it is or seems to be should not be frustrated in their expectations".
What is not recognized as one of the general principles of European Union law?
