...We want to live in a warm climate, with better food, modest & simple people, and we want to live in a rural area; this is important, not in cities!
India has large-scale agroforestry projects we'd also like to get involved with. I am aware that every country has its issues, and some of you think it is a bad idea to move to India/Punjab etc... but that's why I'm here asking what areas are friendly to foreigners wanting to learn and immigrate...
Based on the way you are writing about it, it's clear that you have a romanticized notion of what life in India is like, even in the rural areas.
Maybe you should go to India for a visit, that may dispel some of your illusions.
I don't even know what you mean by "friendly to foreigners". Maybe you're thinking of places like Goa, where tourists come to vacation and spend lots of money, thus driving the local economy.
You might be able to find the kind of ashram you are looking for, but I guarantee you that they won't be practicing Sikhi, because Sikhi is not about sitting inside an ashram chanting mantras and doing yoga (whatever kind).
But that's ok. Sikhi is not for everybody. You will find thousands of baba's and guru's and mahant's when you go to India, each will be running their own dera/ashram and I'm sure you'll be able to find one that suits your requirements.
As far as the information you're looking for, it's simple. Go to the Indian embassy, apply for a visitor visa, buy your plane tickets (most likely you will fly in to New Delhi first), and start packing. If you're that serious, as you keep claiming, then go ahead and go for a visit. You'll make local contacts who can guide you to ashrams and etc.
All the best. I do hope you find what you're looking for. And in the meanwhile, that you don't lose the game in the gamble.
Good Luck!
