ye samāstatra te tāvadyatante citsvabhāvataḥ .
yāvadeko jayatyatra dvitīyaḥ sa nimajjati .. 56

55. [Sanskrit available] It requires therefore a great force of the mind, to overcome its worldly thoughts, and turn them to the channel of truth; as the greater force of the main current of a river, leads its tributaries to the ocean.

56. [Sanskrit available] But the mind is greatly disturbed, when the worldly and spiritual thoughts, press it with equal force to both ways; and it is then, that the greater force leads it onward in either way. (There is no midway like that of the Madhyamikas between this world and the next). Gloss. The worldly and spiritual thoughts being equally forcible, they naturally struggle in the mind, and that which is of greater force overcomes the other.
