The third lessson poses some interesting questions, we´ll take it step by step. Most of the themes of the Bhagavad Gita are in chapters 2 and 3. Conciousness is unchanging and that is the end of all wisdom. Human beings start with being unmanifested, becomes manifested and ends unmanifested.
Karma Yoga, the yoga of action, is introduced. According to Bhagavad Gita all yoga is Karma yoga, wether you meditate, devote or chant, you act.
The three gunas, qualities, was described, they are Sattva, Rajas and Tamas. Sattva are ideas, Rajas are actions and Tamas are slowness. Each person has every quality, and throughout a day we pass through every one. We wake up tamasic, we shower rajasic, and we listen to music that gives us ideas, sattvic.
Religion are also aspects of these qualities: Tamsic is fear based, for instance to follow rituals. Rajasic is reward for action, for instance, being a member of a religious party gives us more power in our church community. Finally, Sattvic is the seeker of knowledge and truth, for instance, the Vedanta. Our goal is to become established in Sattva, but be aware we can do too much meditation for instance, then we cannot function in this world.
Happiness are within you, not in objects of the world. Contentment are always followed by discontentment, you want something and are only happy if you get it, so stop looking outside yourself.
Karma are unconcious thoughts. When we stop having expectations regarding our actions we don´t develop new Karma. It cleanses us from Karma and cultivates a pure mind. If we act with no expectations of reward but simply because we want we reach liberation.
Here comes my question, the idea of, act without expectations, are interesting. Our whole economic system is based on the expectation of: for a dollar I can buy such and such, for ten I get this and for a 100 I get that. Statistics are solely based on the expectations of numbers, the expected value of the dollar, the expected future value of a stock, the expected rate of unemployment etc. You only divert from expected when you have the real numbers. So to believe we actually will do anything without taking into account expectations are beyond me. Yogis do asana´s and we expect to relax in Savasana, find a yogi who does not, I doubt he or she exist.
On the other hand to do it simply because you want to I am all in on. And, that you can experience I have a 1 million dollar in my account, wether I get 1 dollar, 10 dollar or a 100 dollar for 10 sold books, well it is of no interest as it will not increase my wealth in any significant way.
