Mystic's Equations

Jnana = - Illusion = Mind - Expectation
Jnana Yoga = Mind - Expectation

Karma = Action
Karma Yoga = Actionlessness = Action - Expectation

Bhakti = Devotion
Bhakti Yoga = Devotion - Expectation

Yoga = Union = - Expectation

Karma Yoga - Action = Bhakti Yoga - Devotion = Jnana Yoga - Mind
Action = Devotion = Mind
Action = Devotion = f(Intellect)

Functioning = f(Action, Devotion, Intellect)
When Action = Devotion = Intellect,

Functioning = NULL

----> Hence, nothing ever happens

Jnana Yoga = f(-Expectation)
Karma Yoga = f(-Expectation)
Bhakti Yoga = f(-Expectation)
----> Hence, Jnana Yoga = Karma Yoga = Bhakti Yoga

Yoga = Mind - Expectation
But, without expectation there is no mind. So we have:
Mind = Expectation
Yoga = 0
----> Yoga is complete in itself, it can also be termed as nothingness. 'I Am not yet I Am' may be apt way to express this.
