You are much easier to control without having self interest though. If you are no looking out for yourself, conforming to a community, allowing people to walk on you, etc, you have little self-interest and therefore are easier to control. If you care about your freedom, spirituality, Self in general, how will someone control you?
I said if you have no self-interest you are easy to control.
1. If you have no self interest, there is no reason to care about yourself.
2. Without the self (selflessness), there is no individuality.
3. So, with no self interest there is no individuality.
4. With no individuality, there is no freedom.
5. So, with no self interest there is no freedom.
6. If you have no freedom, you are easier to or already complety controlled.
Therefore, with no self interest you are easier to control.
Lack of self-interest leads to selflessness. Accordingly, selflessness destroys self-interest, as you do not care about the Self.
Lack of self-interest contributes to selflessness, which kills individuality. If you are selfless, your self interest has been completely destroyed.
Lack of Self-interest is part of selflesaness, but not totally selfless. But, If you are totally selfless, there is already no self-interest.
Please, do point out my inconsistencies.
