Kundalini experiences, when happening spontaneously i.e without practicing Kundalini Yoga, are those effected by aliens. Regarding Adi Shankara, i suppose he is similar to Buddha and one of his teachings was, If you were to ask any yoga practitioner on kundalini awakening, he would consider your above statment as false; simply because spontaneous kundalini awakening has no other basis other than purva karma. If you were to put forward your basis of alien abductions or alien influence, those people (yogis) might (and very probably wud) smile it off as something completely baseless. May be he was influenced by Maya Dhanava, there are Hindu sects who argue his preachings are not correct. However it is an individual's wish to beleive whatever he/she wants, i am posting my views. well...truly what you might think as the influence of Maya Danava could be your POV alone. I take it that you mean that these things are "symptoms" of spiritual enlightening? These things are not good for humans and they do not happen with the will of humanity. Some forces are trying to influence us, most people beleive these are for good, enlightened beings effect such things. But these are just the beginning. I have debated about this on western forums, a lot of them do not understand that visitation by unknown entities are not good for humans. Those who claim they are brutal are the ones who have experienced the true nature of these entities. Here is one forum where i supported the discussion of a person claiming alien influence is brutal. Not sure how many schools of thot put forth such a view. But spiritual enlightenment as "not good for humans" or not happening with the "with the will of humanity" could be very well debated. Personally, i consider this as your POV alone. UFO Casebook - ALIEN ABDUCTION OR ALIEN SLAUGHTER Assuming it as good is believing in luck. According to Hindu way of life, life is based on Karma. Also we are living in the materialistic age, Kali Yuga where there is little or no spirituality. Believing these things are spiritual enlightenment is, according to the Hindu way of life, absolute folly. There are no scriptures saying the Gods covertly enlighten their devotees this way. Which basically means that (according to you) believing in karma, spiritual enlightenment is absolute folly...Sorry sir, i have nothing to say anymore.
