According to Osho, guidance is not tied to place: seek the master only when it’s absolutely needed and you’ve exhausted your own effort. In most matters you won’t need to call; by not invoking him for trifles, you earn the hundredth case—then you can expect his help "in every possible way," wherever you are.
If it’s truly important and you’ve tried your best, ask and Osho’s help will reach you anywhere; don’t call him for small stuff.
