Justin,
I know exactly where you are coming from about where will the money come from? I recently took retirement knowing what money I received from pension would be a little less than what i would need to pay the bills and maintain a livable existence. But I took the opportunity to follow my bliss without hesitation believing if I don't do it now I may not have a better opportunity to do do. I did plan my retirement and do have a source of income, although it may not be quite enough.
But I am reminded of Joseph Campbell's quote, one that I have experienced time and time again over the past 15 years in my journey;
“Follow your bliss.
If you do follow your bliss,
you put yourself on a kind of track
that has been there all the while waiting for you,
and the life you ought to be living
is the one you are living.
When you can see that,
you begin to meet people
who are in the field of your bliss,
and they open the doors to you.
I say, follow your bliss and don't be afraid,
and doors will open
where you didn't know they were going to be.
If you follow your bliss,
doors will open for you that wouldn't have opened for anyone else.”
There is a caveat to this, one that Campbell noted in his later years. It was how difficult in our time to follow our bliss because of the demands of society. The best thing to do perhaps is to plan your life so you are working toward that bliss and when the right opportunity presents itself {as it did in my case} then take it. What you are doing in planning your yoga classes is right on. Stay with it and don't be surprised when 'doors open' where you had not thought they would be there. You will have to do the 'labor' but the hands of fate will provide the opportunities. This philosophy is a part of what I believe is a mechanism within nature that rewards the soul. Part of the Karma thing.
