You Exist in Past, Present and Future

Kṛṣṇa continues: 'Never was there a time when I did not exist, nor you and all these kings, and never in the future shall any of us cease to be.'

na tv evāhaṁ jātu nāsaṁ na tvaṁ neme janādhipāḥ I
na caiva na bhaviṣyāmaḥ sarve vayam ataḥ paraṁ II 2.12

With this verse begins the essence of the whole Gītā. This is
ātmajñāna, Self-Realization, the knowledge of completion. If you can understand this one verse, you can become enlightened straightaway and enter into eternal bliss.
If you think our souls will also die with our bodies, you are wrong. We were there before our birth and will remain after death. It is not true that any of us will not be in the future.
Listen. You existed in the past, exist in the present and will exist in the future. Your face and body may change but you continue to exist. Then why do we think we will die and why do we fear death? If what Kṛṣṇa says is true, why are we worried about this life and about death? You need to first understand the concept of the past, present and future to enable you to understand what Kṛṣṇa says

Kṛṣṇa says beautifully, 'You were there in the past, you are in the present and you will be in the future; you do not die. You existed before birth and will remain after death. Whatever dies, can never live. Whatever lives can never die.' When Kṛṣṇa says, 'You are the eternal soul,' He means that as a being, you are beyond time.

Here, your deep consciousness says that something is living in you. This quality you wrongly attribute to your body and mind. You are not the body or the mind. As long as you are caught in the past and the future incompletions, you think that you are the body-mind. The moment you come down to the present moment, you are in the eternal space of completion, you experience that you are beyond the body, beyond the mind.
