Maybe the Old Ones are Spirits, or maybe the Old Ones are the Collective Unconscious, or maybe the Old Ones are the accumulated weight of all the culture handed to you by your Mom, your Dad, your Lola, your Etsi, your primos, your titas, your cuyo, your friends, etc. But whatever. If you respect* that weight, that presence, then things will go well with you. If not, if you just jack around with the Old Ones, you could reap some damage.
*Respect does not mean sheeplike following. It could in some cases mean wise, knowledgeable and aware defiance. No one, IMHO, should manifest sexism, racism, heterosexism, etc. just because they saw it in their elders. Defiance can be respectful. "I'm doing things differently from the way you did it, because you gave me the wisdom to grow to my own conclusions as an individual, and I thank you for that."
