We are preaching Kṛṣṇa consciousness movement on the platform of the spirit soul, which we do not see with these material eyes. This is great ignorance. After the death we cry that, "My father is gone," "My son is gone." But where he has gone? He is lying on the bed. Now, even still, we do not come to the understanding what is the difference between the living body and the dead body. There are so many theories, but as I have already told you that we receive knowledge from the perfect person, Kṛṣṇa. He says that within this body the owner of the body is there, and on account of the owner of the body presence, the body is changing. The owner of the body is sometimes in the childhood body; the owner of the body sometimes in a different boyhood body; the owner of the body is sometimes in the youthhood body. Similarly, as he is changing different types of body during this duration of life, similarly, after this annihilation of this body, when it is old . . . just like old garment or old coat, old shirt cannot be used—it is thrown away; another new shirt, new coat is taken—similarly, this body, being annihilated, the soul accepts another body.
This is a real knowledge. Tathā dehāntara-prāptir dhīras tatra na muhyati (BG 2.13). This is explained in Bhagavad-gītā very broadly. Just like here it is said that:
- mātrā-sparśās tu kaunteya
- śītoṣṇa-sukha-duḥkha-dāḥ
- āgamāpāyinaḥ anitya
- tāṁs titikṣasva bhārata
- (BG 2.14)
Our real business, real education, is to understand, "What I am? I am not this body." But that education is lacking. So our main business is to understand that, "I am not this body, and the bodily pains and pleasure, they are due to the change of season." Just like now it is winter season. We are covering our body. In the summer season we do not like so heavily dressed. So this feeling of pains and pleasure is due to this material body.
