Thanks X Katz, you offer a new angle on this for me, thanks, I will mediate on it
I can elaborate on my own understanding.
We can begin with the statement that thoughts are material, albeit very subtle. We can change our thoughts if we change our food or take intoxicants i.e. thoughts are influenced by the material elements because they are material. In Indian Philosophy everything is made of the core 5 elements (often referred to as 27 elements). So the mind is a part of those elements, see verses below if you please
Page 44, Line 2
ਇਕਸੈ ਦੀ ਸਾਮਗਰੀ ਇਕਸੈ ਦੀ ਹੈ ਰੀਤਿ ॥
इकसै दी सामगरी इकसै दी है रीति ॥
Iksai ḏī sāmagrī iksai ḏī hai rīṯ.
The elements and the components are all made by the One; they are held in their order by the One.

ਬੀਸ ਸਪਤਾਹਰੋ ਬਾਸਰੋ ਸੰਗ੍ਰਹੈ ਤੀਨਿ ਖੋੜਾ ਨਿਤ ਕਾਲੁ ਸਾਰੈ ॥
बीस सपताहरो बासरो संग्रहै तीनि खोड़ा नित कालु सारै ॥
Bīs sapṯāhro bāsro sangrahai ṯīn kẖoṛā niṯ kāl sārai.
Bring the twenty-seven elements of the body under your control, and throughout the three stages of life, remember death.

ਇਹੁ ਮਨੁ ਪੰਚ ਤਤ ਕੋ ਜੀਉ ॥
इहु मनु पंच तत को जीउ ॥
Ih man pancẖ ṯaṯ ko jī▫o.
This mind is the life of the five elements.
Page 415, Line 10
ਇਹੁ ਮਨੁ ਪੰਚ ਤਤੁ ਤੇ ਜਨਮਾ ॥
इहु मनु पंच ततु ते जनमा ॥
Ih man pancẖ ṯaṯ ṯe janmā.
This mind is born of the five elements.
In Indian Philosophy, and I am concentrating on the most wise Sri Guru Granth Sahib JI, we are also told that everything that happens is due to the Three Gunas, which are a creation of WaheGuru:
Page 1003, Line 19
ਤ੍ਰੈ ਗੁਣ ਕੀਆ ਪਸਾਰਾ ॥
त्रै गुण कीआ पसारा ॥
Ŧarai guṇ kī▫ā pasārā.
He formed the expanse of the entire universe from the three gunas, the three qualities.
Page 1258, Line 4
ਤ੍ਰੈ ਗੁਣ ਸਭਾ ਧਾਤੁ ਹੈ ਨਾ ਹਰਿ ਭਗਤਿ ਨ ਭਾਇ ॥
त्रै गुण सभा धातु है ना हरि भगति न भाइ ॥
Ŧarai guṇ sabẖā ḏẖāṯ hai nā har bẖagaṯ na bẖā▫e.
Under the influence of the three gunas, the three dispositions, the mind wanders everywhere, without love or devotion to the Lord.
Page 1270, Line 6
ਗੁਰਮੁਖਿ ਤ੍ਰੈ ਗੁਣੀਆਂ ਬਿਸਥਾਰੁ ॥
गुरमुखि त्रै गुणीआं बिसथारु ॥
Gurmukẖ ṯarai guṇī▫āʼn bisthār.
The Gurmukh knows that the universe is the extension of the three gunas, the three dispositions.
The Three Gunas are the problem, because they play on the mind, keeping us detached to maya and in a life of the manmukhs i.e. away from the True One in a life with sorrow and pain. This is their nature of the Gunas and a key to understanding liberation. We must keep in mind the following:
1) The Lord created the universe, the three Gunas, the 5 elements (including the mind) and everything in it:
2) The Gunas play on the mind and are out of our control. In other words they are that which does not let the mind be silent. But...
3) Because the gunas are the creation of the Lord, they are under His will (Hukam) and not our own. So our mind cannot be silent because it is not under our control, it is influenced and played upon by the Gunas. We have thoughts, some we choose and others seem random or even distracting. So;
Even..
by remaining silent, inner silence is not obtained, even by remaining lovingly absorbed deep within.
Because the mind is not ours to control, so inner silence may and cannot be obtained by ourselves. All depends on the grace of the True Guru - of Waheguru. His Hukam. For me hukam is the key to unlocking the message of the Gurus.

My apologies, I didn't intend this to turn into a lecture, but your good question made it clear I had not provided enough explanation
If it raises any questions, I am prepared to add to this.
