Madhvacharya's Dvaita Vedanta and translation of Sarvamoola containing Bhagavad Gita, Upanishads, and Brahmasutra.

Bhagavad Gīta Tātparya

मात्रास्पर्शास्तु कौन्तेय शीतोष्णसुखदुःखदाः। आगमापायिनोऽनित्यास्तांस्तितिक्षस्व भारत ॥ २-१४॥

mātrāsparśāstu kauntēya śītōṣṇasukhaduḥkhadāḥ। āgamāpāyinō'nityāstāṁstitikṣasva bhārata ॥ 2-14॥

O Kunti's Son, the contact of sense objects with senses causes pleasure and pain through the sensation of cold and heat. They come and go and are impermanent. Oh Arjuna, just endure them with firmness.

Gīta Tātparya 2.14

It is attachment to topics, i.e., 'vishayasambhanda' that causes misery.

If one grieves because he cannot see his relatives, the cause is indicated by stating 'matrasparsha' (the contact of sense objects with senses). It means attachment to topics.

बहुचित्रजगद्बहुधाकरणात् परशक्तिरनन्तगुणः परमः ।
सुखरूपममुष्य पदं परमं स्मरतस्तु भविष्यति तत्सततम् ॥
"The one who has created this variegated vast universe with varied forms has infinite power and is of infinite auspicious qualities. He certainly bestows the highest state of bliss to those who meditate on his ever happy essence." -Dwādasha stōtra 4.3
