Signs and wonders point to both the existence of God and the existence of higher beings that visit our planet in amazing craft. I don't know the reason for the UFO's coming here, observation seems the most likely. But we don't have to accept these things for our spiritual search, what matters is within and that's why I chose not to get hung up on what I saw. It coincided with a big uplift in my spiritual efforts and that's where the jewels are to be found.
Wise words.
Based on pure Jnana, my reasoning is that , as Adam Frank says, presently there is no scientific evidence of UFOs visiting our planet. Absence of evidence of course is not evidence of absence.
But all those pictures (most of them are fakes), recounts, and hearsay, have no value on the objective plane. Conceptual reasoning and assigning degrees of probability is one thing.
Hard evidence, 100% or even 99% probability is another.
Steve, As to the quotes from Yogananda, many things have been misquoted or even distorted. If coming from an official printed SRF material, that's a certain reference. If coming from talks of his direct disciples, it is also acceptable. If coming from personal words from Bakhtananda to you, then it is also acceptable, providing you are remembering well.
If coming from other sources, well, with all due respect, there are even people who use the name of great masters to illustrate their own personal views, unfortunately we all have a certain age, we know that and are not so naive to believe everyone.
