12. The word 'spirituality' has no meaning at all, imho

What is 'spirituality'? Here's the wiki definition, so vague as to be totally useless:

Definition[edit]
There is no single, widely-agreed definition of spirituality.[5][6][note 2] Surveys of the definition of the term, as used in scholarly research, show a broad range of definitions, with very limited similitude.[7]

According to Waaijman, the traditional meaning of spirituality is a process of re-formation which "aims to recover the original shape of man, the image of God. To accomplish this, the re-formation is oriented at a mold, which represents the original shape: in Judaism the Torah, in Christianity there is Christ, for Buddhism, Buddha, and in Islam, Muhammad."[note 3]

In modern times the emphasis is on subjective experience.[9] It may denote almost any kind of meaningful activity[1][note 4] or blissful experience.[3] It still denotes a process of transformation, but in a context separate from organized religious institutions, termed "spiritual but not religious".[10] Houtman and Aupers suggest that modern spirituality is a blend of humanistic psychology, mystical and esoteric traditions and eastern religions.[11]

Waaijman points out that "spirituality" is only one term of a range of words which denote the praxis of spirituality.[4] Some other terms are "Hasidism, contemplation, kabbala, asceticism, mysticism, perfection, devotion and piety".
