Knowledge has been told by many books and sages in the world how salvation will be attained. Most important is your karma, your salvation or rebirth is decided based on what you do. How many roles are you giving to the public interest in actions? Everybody performs karma for their own interests in life, but when your deeds do not involve themselves as well as the welfare of the society, then your karma will be considered as Sathkarma.
Human birth is rare and you don't need to be born again in human form, therefore, correct this life and put it in the right deeds in the right direction. The method of salvation is stated differently in every era. It is believed that the easiest method is that of Kali Yuga, even if you make a small donation in this war, it will also be counted in your big sat karma.
It is your mistake to consider yourself what you are getting in this life. When a person surrenders all his deeds and everything to God, then he can get away from the bondage of virtue and sin. We can earn anything in this life, but when we go from the world, then we will not be able to take anything with us, which will remain the same, and in the end, we will be absorbed in that ultimate power. With this hope, the art of living life is considered as salvation.
