Karika 15

भेदानां परिमाणात् समन्वयाच्छक्तितः प्रवृत्तेश्च। कारणकार्यविभागादविभागाद्वैश्वरूपस्य ॥१५॥

bhēdānāṁ parimāṇāt samanvayācchaktitaḥ pravr̥ttēśca। kāraṇakāryavibhāgādavibhāgādvaiśvarūpasya ॥15॥

[भेदानां परिमाणात् समन्वयात् शक्तितः प्रवृत्तेः च। कारण कार्य विभागात् अविभागात् विश्वरूपस्य॥
bhēdānāṁ = differences; parimāṇāt = the effects; samanvayāt = integration of; śaktitaḥ = the strength of; pravr̥ttēḥ = tendencies of the activities; ca = and; kāraṇa = cause; kārya = act; vibhāgāt = dissecting; avibhāgāt = undissected; viśvarūpasya = the universal form;]

The differences arise due to integration of the resulting effects, as per their respective strengths, driven by tendencies, its cause, and acts, by dividing the undivided universal form.
