Acharya Prashant explains that the use of animal products in musical instruments, sports equipment, and pharmaceuticals is a matter of human sensitivity and compassion. He notes that while technology exists to create cruelty-free alternatives through material science and laboratory simulations, manufacturers often choose animal-derived materials because they are cheaper and more readily available. He highlights that as an individual's understanding and sensitivity grow, they naturally find it impossible to use products made from animal remains, such as leather or gut strings.
