I know of people (really one) like Jay Dyer (Jay's Analysis) besides having experienced acquaintance of three Greek Orthodox. Only with one did I get an exercise on the "filioque". The two others had flaked out on Orthodoxy. One became an evangelical and the other was like a syncretic Buddhist.
After that, I dismiss all the Greek Orthodox and think they owe everybody a sincere apology about the filioque, and I prefer to make fun of them for navel-gazing or omphaloskepsis, from the Ancient Greek words ὀμφᾰλός (omphalós, lit. 'navel') and σκέψῐς (sképsis, lit. 'viewing, examination, speculation'). The monks of Mount Athos, Greece, were described as Omphalopsychians by J.G. Millingen, writing in the 1830s, who says they "...pretended or fancied that they experienced celestial joys when gazing on their umbilical region, in converse with the Deity", etc.
As far as a more serious or worthwhile response, I may not have it. From the "Monk's Ladder", Guigo the Carthusian recommends a four rung ladder, reading as the bottom or first rung, meditation as the second rung, prayer as the third rung, and contemplation as the fourth rung. According to him the fourth rung can't be forced but the way up to it can be cultivated and with God's grace can be obtained and then with grace further guided to benefit the Church and the soul, etc.
