What do you want to do sadhana for? The aim should not be the satisfaction of egoism: "I want to be a great yogi; I shall have so much power and with that power I shall establish myself in the world." All such thoughts must be thrown far away.
The last thing you want to do is raise taxes in the middle of the recession because that would just suck up and take more demand out of the economy and put businesses in a further hole.
