Karika 38

तन्मात्राण्यविशेषास्तेभ्यो भूतानि पञ्च पञ्चभ्यः। एते स्मृता विशेषाः शान्ता घोराश्च मूढाश्च ॥३८॥

tanmātrāṇyaviśēṣāstēbhyō bhūtāni pañca pañcabhyaḥ। ētē smr̥tā viśēṣāḥ śāntā ghōrāśca mūḍhāśca ॥38॥

[तन्मात्राणि अविशेषाः तेभ्यो भूतानि पञ्च पञ्चभ्यः। एते स्मृता विशेषाः शान्ता घोराः च मूढाः च॥
tanmātrāṇi = the sensations (tan-matras); aviśēṣāḥ = not so distinct; tēbhyō = from these; bhūtāni = gross elements; pañca = five; pañcabhyaḥ = from the five; ētē = these; smr̥tā = remembered, from memory; viśēṣāḥ = distinguished as; śāntā = peaceful; ghōrāḥ = agitated; ca = and; mūḍhāḥ = dull; ca = and;]

The five not so distinct sensations (tanmātrāṇi) distinguish the five gross elements as peaceful, agitated, and dull, with the aid of memory.

Sensations along with memory help us to distinguish the five elements, and thus the world around us.
