When such a self-satisfied person realizes the Absolute Truth, he neither rejoices nor laments. Seeing all beings equally, he attains transcendental devotion unto Me.
Bhagavad Gita - Chapter 18 - Moksha Yoga - The Yoga of Supreme Perfection
Through such devotion that person knows Me in truth. Thus, knowing Me in truth he enters My realm.
Although one may constantly engage in various activities, by My mercy, those who take shelter of Me reach My eternal abode.
Consciously renouncing all activities unto Me, considering Me to be the supreme goal and taking shelter of the process of devotion, always think of Me.
By My mercy, all your troubles will be overcome if you think of Me. However, if out of false ego you ignore Me, you will perish.
If due to false ego you think, “I will not fight,” your decision will be useless because your very nature will urge you to do so.
Being bound by your intrinsic nature, the very activity that you now refuse to perform due to bewilderment will inevitably be carried out by you, O son of Kunti.
O Arjuna, the Supreme Controller resides in the hearts of all living beings. By His illusory energy He directs all their activities as if they were mounted on a machine.
O Bharata, take shelter in Him with all your heart and by His mercy you will achieve everlasting peace and the Supreme Abode.
I have thus disclosed to you that knowledge which is the most confidential. Deliberate upon it and do as you wish.
