Yogadṛṣṭisamuccaya - And in the absence of that (state), the statement that the worldly and the liberated (are different) becomes meaningless. The destruction of its own nature by means of reasoning is considered as the true (nature) of this (self).
Meaning - And in the absence of those (two) states, the statement that the worldly and the liberated (are different) becomes meaningless. Therefore, the true (nature) of this (self) is to be considered as the destruction of its own nature by means of reasoning.
Vivecana and as stated above, in the absence of those (two) states, the statement that the worldly and the liberated (are different) would become merely a meaningless verbal expression, because the meaning is the essence. Therefore, in this manner, the self should be considered as the true (nature) by the reasoning of the nature-destruction (svabhāvopamarda) - that is the desirable (iṣṭa) view. This nature-destruction has the characteristic of destroying the other by means of the other, i.e., it has the characteristic of destroying the other-than-that by means of that.
As proved and demonstrated above, in the absolute non-changing eternal singular nature, the two states can never occur. Thus, in the non-changing (aparināmī), the absence of those (two) states, the self being worldly and liberated will not occur. So, the conception of these two different states - the worldly with the nature of the sub-human etc., and the liberated due to the cessation of the cycle of rebirth - this conception becomes meaningless, devoid of meaning, merely a verbal expression, a mere statement, a mere conception, not the true essence-nature. This is inappropriate, contradicted by the observed and the desired, because the worldly and the liberated are definitely the two different states, observed and desired, so the absolute non-changing singular nature does not fit.
From this, the implication is that the occurrence of the two states of the worldly and the liberated is itself what is to be considered as the true (nature) of the self by the reasoning of the nature-destruction (svabhāvopamarda).
The destruction of one nature by another nature - that is the nature-activity (svabhāvavṛtti); and in its absence, the absence of those (two) states, the worldly with the nature of the sub-human etc., and the liberated due to the cessation of the cycle of rebirth - this is merely a meaningless verbal expression due to the lack of meaning. Therefore, in this manner, by the reasoning of the nature-destruction (svabhāvopamarda) - having the characteristic of destroying the other by means of the other, the self should be considered as the true (nature) by the reasoning (nyāya), the desirable (iṣṭa) view.
