Our Existence Is Just Perfect and Nothing More Is Needed
If we can understand that our existence should not be altered but only be experienced, our execution will become perfection. The unfulfillment, the incompletions and the yet to be achieved feeling should not be cherished in our existence because in our existence nothing more needs to be added, but in our actions there should always be so much of patience as if only these actions would save our life.
How To Know If You Have Lived Your Life Fully?
If you are feeling you' ve not achieved, or if you are feeling the unfulfillment, if you are feeling life is not enough, be very clear you are living just with memories.
You are not alive, that is why you don't feel you are living. You don't feel the fulfillment. For example: "Do not try to add years to your life, add life to your years." Bring life to your years, not years to your life. If your body is running based on the fuel of fear and greed, you'll be running with the past memories, recorded system.
Naturally, you will not tend to move your body more. One more thing, whenever you move your body with fear and greed, you feel so much of irritation. If you are living, if you are alive, you'll feel so fulfilled, you'll feel you are here for too long time.
Unfulfillment Can Dull Your Senses
So beautifully Nachiketa says when the senses lose their vigor, even the longest life is useless; short.
अपि सर्वं जीवितम् अल्पम् एव अपि सर्वं जीवितम् अल्पम् एव अपि सर्वं जीवितम् अल्पम् एव api sarvaṁ jīvitam alpam eva api sarvaṁ jīvitam alpam eva api sarvaṁ jīvitam alpam eva.
When more and more sense objects are enjoyed with the unfulfillment, incompletion, senses become duller and duller and duller. Senses loses the vigor.
