b a where a represents the motion of the moon in a given time and b the motion of the sun in the same time, it follows that a - b is the moon's elongation or the space gained by the moon over the sun in the given time. If we regard separately the spaces travelled by the sun and the moon in this time, we might say that together they have done a+b. This a+b, then, is the yoga, while a-b is the tithi. To derive the yoga from the tithi, we make use of the formula a-b+2b= Yoga. just as we derived the nakshatra from the tithi by means of the formula a-b+b. (Sec. 36 supra.)
