As a younger and far more naive kid I was drawn to Aleister Crowley for the motto he espoused in his "magickal journal," The Equinox: The method of Science, the aim of Religion. Much of his writing proposes a few experiments you can try for yourself; the first line of "Liber E vel Exercitiorum" reads, "It is absolutely necessary that all experiments should be recorded in detail during, or immediately after, their performance." Crowley was interesting in that he tried to bring an empirical, albeit subjective (since the target of study is the mind, psychology, subjective experience itself) and non-objective, non-quantitative approach to techniques of mysticism - meditation, breath work, and ritual, in particular. Buddhism also contains some experimentation of its own - I am quite fond of Daniel M. Ingram's work with the "fire kasina" technique, in which clear steps for reproducing the result are given, and falsifiable claims are made about what (note: subjective!) phenomena will occur as a consequence of the experimental procedure. It is possible to reproduce such claims for one's self, given sufficient time and practice. In the sense that some spiritual traditions and philosophies have as their subject of study the mind, and employ empirical techniques to gain insights into it, yes, I would say they are arguably sciences of mind.
