One does not know when the last breath will be.

 The glories of Divine Name recitation (japa) that can be understood by actually doing japa, is not understood by reading, saying or hearing about it. The glories of a satisfying meal are by actually eating, are not understood by talking about meals. Laddoos (sweets) look good, but any amount of talking about it, will not be the same as actually eating it.

This world is ever changing is our visible and evidential experience. That too you do not believe? What to do? See your body and mine, how much it has changed? And it is continuing to change. Someone who had seen me in childhood and sees me now, they cannot even recognize. This world is only changing constantly, every moment. It is only an accumulation of changes. Those changes itself is called life. There is not a moment that is not changing – this is the point.

You are comfortably sitting free of concern! It is a surprising thing! There is no certaintly of even in a single moment. One does not know when the last breath will be. There is no certainty that the breath that is leaving this body, will return again. There is no trust or confidence what so ever. There is no guarantee. It will not remain. It cannot remain. It is going away. It is only a delusion that we think we are living. It is completely false, death is taking place every moment. Every moment the dying is happening. You think it is secure. There is no attention given in this direction. We talk about it, we hear about it, but there is no awareness in this direction. You consider yourself to be stable, it is a surprising thing.

By lying, cheating, dishonesty, deceit, being unscrupulous, you have accumulated wealth. For sense enjoyments you have committed so many sins, done so much injustice, have committed so many atrocities.

God has said in the Gita -


"Bhogaishvarya prasaktaanaam tayaapahchetasaam
Vyavasaayaatmika buddhih samaadhau ne vidhiyate." (Gita 2:44)

One who is attracted to enjoyment of pleasures and hoarding, that one cannot even have a firm resolve to realize God. He will be far from God Realization, but worst yet, the firm determination that I want to realize only God, I want to only gain salvation - he will be unable to firmly resolve towards this aim. Simply speaking, as long there is desire within, as long as there is attraction and importance given to worldly things and enjoyments, till that time, however much you hear these talks, you will be unable to resolve towards God. When the objective, the goal itself is not firm, then how will God Realization be possible?

From summary of discourse in hindi . by Swami Ramsukhdasji

you become Krishna conscious then you get permanent life.

We are not proprietor of this body. We are occupier. Just like a rented house: the proprietor and the tenant are different. So I am the spirit soul. I am not proprietor; I am simply occupier. The proprietor is the Supreme Personality of Godhead. He is giving me a particular apartment according to my capacity of paying rent. According to our karma or work, we get a body, either as a king's son, a cobbler's son, a dog's son, a cat's son, a tree's son or a plant's son. If you are in a rented apartment, you are given the license to occupy the room. So mistake is that we do not know the owner, and we are improperly using our occupation. The direction is there, the director is sitting there. He's always helping you. But the disease is that we are claiming to be owner and want to act according to our whims, and that is material condition. Krishna said "Don't think we did not exist in the past. We are existing at present, and we shall continue to exist in the future." Exactly like that "I existed in one apartment, now I am existing in one apartment, and I shall exist in another apartment." I am spirit soul. I am simply changing different apartments. Because I am eternal, there is a life, where I haven't got to change apartment. I get permanent residence. That is spiritual life. So long you are in material existence you have to change different types of body. But if you become fit for spiritual existence, you get rid or get out of this entanglement of changing bodies. This is Krishna consciousness movement. We are teaching our people that "you become Krishna conscious then you get permanent life."

The Supreme God is infinite; everything about Him is infinite

Human birth is best due to endowment of the special quality of power of discrimination between good and bad and eternal and non-eternal. Physical bodies are in the grip of numerous births and deaths, and are subject to many other drawbacks. This renders the physical body to being non-eternal. If this physical body is non-eternal then the body’s sense organs must also be non-eternal and whatever is perceived by non-eternal sense organs must also be non-eternal. Therefore, if there should be any eternal entity, it must exist beyond the comprehension of human material non-eternal sense organs.
    In the Mahabharata, Arjuna was blessed with divine eyes, so that he may witness the vishwarupa of Krishna, a dazzling sight. Thousands were present at Kurukshetra when Krishna revealed His Virat form, yet Arjuna was the only one to see Him like that. Why?
    The Supreme God is infinite; everything about Him is infinite. He has created countless species to a plan. If one accepts that human beings can determine their own cause by means of material senses, mind or intellect, then that will be a mentally or intellectually concocted thing. That will not be Reality. If Reality is in fact Reality, then He must always exist. What is the Truth? Why do we wish to be eternal? Why are we eager to learn and to experience bliss? We are a part of the Supreme – so we are like the Supreme in some respects. He is Sacchidananda and so are we. Sat in Sanskrit means eternal life, chit is eternal knowledge and ananda is eternal bliss. Soul is sacchidananda. We were given this limited body to know our true identity. Our duty is not to hanker after temporary bliss, but to have eternal bliss. We have to find ways to realise our true identity to become servants of Sacchidananda. Since we are part of the Supreme Lord, it is our primary task to serve Him or to act in a way that pleases Him. Once we realise Him, we will also realise other eternal truths, and know that not only He, but His Associates, too, do not take birth, but descend.
