StillOne pointed me to this thread, so I'm going to post my friend's chart, as he also has this pattern (same basic birth-stretch in October).
I post it in part because he is NOT a spiritual person -- in fact he's about one step from being an atheist. He was raised (German) Catholic, and left the church as a teen/adult, becoming one of the few people in his family to reject faith. He isn't impolite, but he is skeptical of things he can't see, touch, hear, etc. I'll get back to this in a sec. But I once told him about a near-death experience I had because he asked how I could be so certain we had a soul. I told him what had happened, and he listened, but while he seemed interested, it wasn't something he could connect with as he hadn't shared it himself (nor would I try to insist someone accept souls just because I said so). Now, in general, we have the sort of relationship where he listens very closely to and respects my opinions/experience. I seem to occupy a special place in his orbit in terms of trust. But this was a line he simply couldn't cross on "faith" or "trust." Again, he was not the least disrespectful and I've never heard him make fun of others for their beliefs, although I have met far more militant atheists who do. On his FB status, his comment on religion is telling, "No thanks, but you go ahead."
It's a little tongue-in-cheek, but not vicious.
Now, I say all that as a balance to this as pattern as necessarily tied to a spiritual expression. I might, rather, suggest that it could have a role as bringing together a lot of energy which will either overburden the native with the constant "adjust" of the yod, OR catapult him/her into breakthrough insights if the adjustments can be managed ... and possibly both at different points in the life. I have a yod myself, but not like these. But I will say that yods NEVER seem to be *completely* resolved.
Now, regarding my comment on the fact my friend is a skeptic. I think some of this may owe to the fact he has his Venus-Neptune conjunction in his *first house*. And bless him, he's occasionally completely CLUELESS. I joke about being his "social interpreter" but it never ceases to amaze me how he can miss or overlook things that other people find blindingly obvious. Also, throughout his life, he's told me that he tends to be "caught by surprise" by other people's thoughts about him/feelings for him (especially women). Sometimes he sounds just amazed, other times a tad resentful that he can't SEE it ahead of time. And I think this pattern is fairly consistent throughout his life, which -- combined with his training in critical thinking via both philosophy and history -- makes him adopt a skeptical view in order to avoid being "taken."
Now, a final thought on this pattern. I've never read anything about it before, either, but I have seen it once before in the chart of a talented female (SF) author.
When I first saw it, however, I didn't see a pentagram, but a house.
Given that yods create tension that's difficult to balance, and looking at how "hard" aspects work in other cases, let me try comparing this to the T-Square versus the Grand Cross. A T-Square can be more frustrating because it's missing the "balance" of the Grand Cross. In youth, a Grand Cross is tough. But all those squares create a weird balance. Likewise with this one, the triple yod might actually provide some ways to balance it that a single yod is missing (as the possessor of a single yod). The point planet(s) at the apex of the Minor Grand Trine, and the "feet" at the root of the side trines are the propelling factors. A single yod offers only one "east" aspect: the sextile. But this "house" or pentagram offers quite a few. Focus on the sextiles and trines as ways to ease the stress.
