In the Bhagavad-gītā also it is said, īśvaraḥ sarva-bhūtānāṁ hṛd-deśe 'rjuna tiṣṭhati. (BG 18.61) Īśvaraḥ, the supreme Lord is situated in everyone's heart. Your heart, my heart, it is particularly mentioned in the heart. We are searching out, where is the soul, where is the Supersoul but it is in the heart. And we see also so long the heart is going on beating the living condition is there as soon as the heart stops everything finished. And the śastra says also, īśvaraḥ sarva-bhūtānāṁ hṛd-deśe 'rjuna tiṣṭhati. Now you find out where is the Supersoul and the soul but because you cannot find out it does not mean that there is no soul, no Supersoul. That does not mean. That is your imperfectness of knowledge, or process of knowledge. And how you can find out? The magnitude of the soul is stated in the śastra, 1/10000 part of the tip of the hair. We cannot measure even the tip of the hair, and why, how we can measure it? And because we cannot find out we say there is no soul. No. There is soul.
keśāgra-śata-bhāgasya śatadhā kalpitasya ca jīvaḥ bhāgo sa vijñeyaḥ sa cānantyāya kalpate (CC Madhya 19.140) Therefore we have to see through the śastra, not by our blunt eyes and senses, that is useless, adukik. Those who are bringing spiritual master as spiritual matter to be, to be subjected to the experimental knowledge, it is not possible.
