I'm in a very similar, or, a little more difficult situation because the country - Hungary - I live in has no Indian community, not to speak of Devi temples. I read several texts, I heard several opinions with regards to the necessity of a guru. I think that taking diksha would be great, but since this is out of the question at the moment, I'll do the best I can. I chose two shorter texts I recite at least once a day, and I chose two mantras of Kali I chant on japa on a daily basis. I ordered some puja books from India, they are nice, but I feel that you can't learn any upasana by reading books. So yes, I'm totally eager to find a lineage and a guru, and take diksha and shiksha from him. However, just flying to India for a huge amount of money and wandering around waiting to meet the guru in a miraculous way, well, if I was 20 years younger I might even try, but now - no way. So what I'm doing is trying to establish connections in India so I might find a parampara and a guru I can trust wholeheartedly. It's not easy, though. I have emailed at least 20 Kali temples all over India, and only one of them replied. I hope I may find some senior Shakta sadhakas on this forum. If you're one of them, don't hesitate to contact me.
