Answer: Yes
Explanation: In an attempt to propose unconventional models of spiritual development, Fowler and Wilber propose a higher and more trascendental vision of spirituality that enables us to expand our levels of faith and consciousness in life over time. In connection to this, I consider it helpful for human beings to conceive spirituality in connection with 'the trascendental', since it may enable us to see beyond and to try to challenge our inner selves so as to grow spiritually.
