Do all prescribed acts such as war etc., (here a duty) free from desire or selfishness and devoid of fear, with a mind focussed on the self. Surrender all acts to Me, the Lord of all, who constitutes the inner pervading Self of all beings. ‘Adhyatma-cetas’ is that mind which is focussed on the self by knowledge of the essential nature of the self as declared in hundreds of Vedic texts. That this individual self constitutes the body of the Supreme Self and is actuated by Him, is taught by Shruti texts like: ‘He who has entered within, is the ruler of all beings and is the Self of all’ (Tai.Ar., 3.11), ‘Him who has entered inside and is the doer’ (Ibid., 3.23), ‘He who, dwelling in the self, is within the self, whom the Self does not know, whose body is the self, who controls the self from within—He is your internal ruler and Immortal Self’ (Br.U., 3.7.22). Smrti texts also speak in the same manner: ‘Him who is the ruler of all’ (Manu, 12.122). Shri Krishna will say later on: ‘And I am seated in the hearts of all; from Me are memory, knowledge and the faculty of reason’ (15.15); ‘The Lord, Q Arjuna, lives in the heart of everything causing them to spin round and round by His power, as if set on a wheel’ (18.61). Hence, dedicate to Me, the Supreme Person, all actions considering them as done by Me, by contemplating on the self as actuated by Me by reason of Its constituting My body. And do every thing, considering the actions as My worship only; becoming free from desire for fruits and therefore free from selfishness as regards actions, engage in acts like war etc., devoid of ‘fever’, i.e., the excitement caused by passions like anger. Contemplate that the Supreme Person, Lord of all, Principal of all, gets done His own works only for the purpose of getting Himself worshipped with His own instruments, namely, the individual selves which belong to Him and are His agents. Become free from selfish attachment to action. Also be free from the feverish concern originating from such thoughts as ‘What will become of me with an ancient, endless accumulation of evil arising from beginningless time?’ Perform Karma Yoga with ease, for the Supreme Person Himself, worshipped by acts, will free you from bondage. His Lordship and Principalship over all are settled by Shruti texts like: ‘Him who is the supreme and great Lord of lords, Him the Supreme Divinity of divinities’ (Shve.U., 6.7), The Lord of the Universe’ (Tai.Na., 11.3), ‘The Supreme Ruler of rulers’ (Shve.U., 6.6-7). Ishvaratva is the same as Sheshitva, which means controllership.

Shri Krishna declares that this alone is the essential meaning of the Upanishads:
