Arjuna was military man. He had his energy—to fight. So he fought for Kṛṣṇa. That means he engaged his energy for Kṛṣṇa. He did not change his military position. So we haven't got to change our position. Simply we have to transfer the energy for Kṛṣṇa. That is called yoga-sannyasta-karmāṇam.
Not that we cease to work. Work you must. Without work, nothing can be done. But if you spare your energy in that way, for Kṛṣṇa's work, then yoga-sannyasta-karmāṇaṁ jñāna-sañchinna-saṁśayam. And in that position . . . why I shall engage my energy to Kṛṣṇa? That requires knowledge. That is real knowledge that, "Why? Why I shall?" Because you are a part and parcel of Kṛṣṇa, therefore you are meant for. Your energy is for Kṛṣṇa, nothing else.
Several times we have discussed this point, that this hand, this work of my hand, is a kind of energy of my body. Now, this hand is meant for working for this body. Similarly, mamaivāṁśo jīva-bhūtaḥ jīva-loke sanātanaḥ (BG 15.7).
The living entities, they are all parts and parcels of the Supreme, and therefore the energy . . . that is . . . that energy also part and parcel. That energy also part of Kṛṣṇa. Kṛṣṇa has got unlimited energy, and our energy is just a part of energy. That's all, part of energy.
So therefore our energy should be spent for Kṛṣṇa. Jñāna-sañchinna-saṁśayam. And that, I mean to say, utilizing the energy for Kṛṣṇa should be based on pure knowledge, pure knowledge that how . . . what is that pure knowledge? That, "I am meant for Kṛṣṇa, or I am meant for God, so I should utilize my energy for that purpose." Ātmavantaṁ na karmāṇi nibadhnanti dhanañjaya. So anyone who is working in this way, then he hasn't got to suffer the consequence, good or bad, of any work. He is free from the reaction of this work.
