Bhagavad Gita Chapter 3 Sloka 31 (3.31)

ಯೇ ಮೇ ಮತಮಿದಂ ನಿತ್ಯಮನುತಿಷ್ಠಂತಿ ಮಾನವಾಃ।
ಶ್ರದ್ಧಾವಂತೋನಸೂಯಂತೋ ಮುಚ್ಯಂತೇ ತೇಪಿ ಕರ್ಮಭಿಃ॥೩೧॥
ye me matamidaṃ nityamanutiṣṭhaṃti mānavāḥ|
śraddhāvaṃtonasūyaṃto mucyaṃte tepi karmabhiḥ||31||
Gist of the sloka:
One who believes in this teaching of mine and lives according to it, will escape from the bounds of karma.
Explanation:
Everything which is happening through me, is because of Lord. Everything I am doing, is like a worship to Him. What is beneficial to me, is known to the Lord better than me. I will therefore do not exercise any desire for a reward but will accept whatever comes my way, as His blessings. This is how I will live.
This should be how we believe and act in our life, always.
Mankind who believes in the above in every moment of their life, are known as human beings, gynani and one who has sense of humanity. One who has no Tamasic or Rajasic and does his karmas with sense of renunciation, will have elevated knowledge. They will slowly rise and become eligible for mukthi.
If you see, our own actions create barriers for us. If in case, we are doing the karmas with right knowledge, the same karmas become steppingstones and eliminates the attachment of karmas to us.
