Here are several translations of the first few sutras from different sources:
1.1 Now, instruction in Union.
1.2. Union is restraining the thought-streams natural to the mind.
1.3. Then the seer dwells in his own nature.
1.4. Otherwise he is of the same form as the thought-streams.

1.1 Now begins the sacred instructions of union.
1.2 Union by stopping mind activity.
1.3 At this time the seer enters their own true state.
1.4 At other times the mind fluctuates and the seer
identifies with this. The seer is then elsewhere.

Asuri, do you need anymore translations to show that you are in error? Finally, we can look more precisely at the etymology of nirodha:
Nirodha: Release, liberation, cessation, cancellation, nullification, dissolution, stillness, emptiness, disappearance, or extinguished, hence a rested open free and relaxed state. The prefix, nir, means means cessation, absence, devoid of, without, empty of, or freedom from something, while “rodha” means limitation, prison. wall, place of confinement, or obstacle. Hence citta-vrtti nirodha means a freeing up of the limitations of the mindfield (citta-vrtti).
