Hearing ,seeing seeing, touching etc. are the functions & activities of gross organs ( Sthula indriyas) of the human body.
But the soul is without a (subtle) body) , without muscles (a gross body). So the soul is just a witness , he is free from all the material pleasures or businesses of the world. It is just the sustainer of the activities of living beings.
Here in Isha Upanishad-8th Mantra Isha Upanishad-8th Mantra it is described that the soul is not made up of Subtle or gross body or Indriyas.
स पर्यागच्छुक्रकायमव्रणस्नाविरं शुद्धमपापविद्धम् ।
कविर्मनीषि परिभूः स्वयम्भूर्यथातथ्यतोऽर्थान् |
व्यदधाच्छाश्वतीभ्यः समाभ्यः ॥8||sa paryāgacchukrakāyamavraṇasnāviraṃ śuddhamapāpaviddham |
kavirmanīṣi paribhūḥ svayambhūryathātathyato'rthān
vyadadhācchāśvatībhyaḥ samābhyaḥ ||He, the self-existent One, is everywhere-the pure one, without a (subtle) body, without blemish, without muscles (a gross body), holy and without the taint of sin; the all seeing, the all knowing, the all-encompassing One is He. He has duly assigned their respective duties to the eternal Prajapatis (cosmic powers).’
Here is the The Prashna Upanishad mantra which tells us that after death the soul enters into another body with the senses clinging to the mind.
तेजो ह वा उदानस्तस्मादुपशान्ततेजाः ।
पुनर्भवमिन्द्रियैर्मनसि सम्पध्यमानैः ॥9॥tejo ha vā udānastasmādupaśāntatejāḥ |
punarbhavamindriyairmanasi sampadhyamānaiḥ || 9 ||
9. The external fire têjas verily is udâna. Therefore the fire being extinguished, one again enters another body with the senses clinging to the mind.Shankara’s Commentary: - Therefore, when a man’s natural fire is extinguished, then one should know that his life is spent, i.e., that he is dying; he enters another body. How? along with the senses such as speech, etc., clinging to the mind.
This means in subtle organs (Sukshma Sharira) still remains after death , but they are clinging to the mind. That means they are fully merged with mind and unlike gross organs can’t actively function . Like organs function in living beings i.e. hearing ,seeing seeing,touching touching etc.
Conclusion – So by looking at the above verses we can say that even the sukshma indriyas still remain attached with soul after death , but because they are completely merged in mind do not function as human organs generally function when alive , and because they are in subtle form and not in gross can’t hear, speak, taste and see.
