You’d be best served if you practice gratitude. That’s what every spiritual guru says. It’s also what our shastras / scriptures teach us.
The idea is simple. To identify basic things from our lives and be thankful for them. Got food on the table for all the 3 meals of the day? We’re already better off than maybe half the planet. Wow, what a start!
The moment we begin to look at the world this way, finding the positives in everything, the chances of our material success multiplies manifold. Why? Because negativity and self-doubt get booted out the door, one thought at a time, as we are thankful about more and more things going our way.
Life is all about how everything that happens is part of a long story of lessons. We may just need to appreciate the flow and learn from them teachings. This then automatically converts from material success to spiritual success. Because once we are grateful for everything, then we want nothing more, and eternal peace follows.
