To translate something one does not just look at the literal meaning of a word, because every word will actually have loads of meanings(this is not just peculiar to Sanskrit, it is common in every language) but the meaning that is intended can only be understood by looking at the context of the passage it occurs in, and in the wider context of the text itself. It then becomes clear exactly what Patanjali is intending to mean.
There is no doubt about it, that Patanjali is calling for the total cessation and stoppage of all vrittis. This is clear from his direct reference to gunas, and those of us who know Samkhya philosophy know that the gunas are forces/activities within the substance of prakriti, which are always in incessant activity and have been in such activity since the beginning of time when the first contact between consciousness and primordial matter(Moolaprakriti) took place. At the time of dissolution, the guna activity comes to a halt, matter reverts back to its primordial state and consciousness becomes fully illuminated now that nothing is occluding its vision.
Patanjali makes a direct link between his Yoga psychology and the gunas, thus it is very clear that the guna activity are psychologically experienced as mental activity(This point is also ratified by the Gita) This is actually made clear in Samkhya philosophy itself that the gunas have both objective and subjective effects. The rising of air, or the upwards movement of a flame, or the floating of something is attributed to the principle of buoyancy(sattva) It is also responsible for the subjective feeling of pleasure and higher mental states like inspiration, cognition. Likewise, the principle of activity(rajas) is attributed to intense movement, winds, violent activity. It is also responsible for the subjective feelings of passion, lust, excitement, desire, fear.
It is clear by logical deduction then, that as long as there is any guna activity, consciousness still remains imprisoned and entangled. It is only when it is CEASED that consciousness is liberated. Hence why Patanjali is calling for total CESSATION of the vrittis. This is indeed the correct definition of what Yoga is, and like I said earlier, it gives the game away on what exactly needs to be done.
Of course Asuri can continue to believe in wrong definitions if he wants. Nothing is changed there. Asuri does not have a correct understanding of anything in Indian philosophy. He is intent on distorting everything in Indian philosophy to conform to his Christian beliefs. Anybody that wants to take his views seriously despite exposure to the correct learned view, should be left to their own devices.
