First of all, Maslow's theory is not universally accepted.
"While the hierarchy remains a very popular framework in
sociology research and
secondary and
higher psychology instruction, it has largely been supplanted by
attachment theory in graduate and clinical psychology and
psychiatry."
Second of all, at the very top of the hierarchy is
self-actualization:
""What a man can be, he must be."
[11] This quotation forms the basis of the perceived need for self-actualization. This level of need refers to what a person's full potential is and the realization of that potential. Maslow describes this level as the desire to accomplish everything that one can, to become the most that one can be.
[12] Individuals may perceive or focus on this need very specifically. For example, one individual may have the strong desire to become an ideal parent. In another, the desire may be expressed athletically. For others, it may be expressed in paintings, pictures, or inventions."
These goals or needs do not require religion.
