Association with the modes of nature determines one's actions, position, and destiny throughout the material world.Listen — Srila Prabhupada Uvaca
Pradyumna: [leads devotees in chanting] Oṁ namo bhagavate vāsudevāya. Oṁ namo bhagavate vāsudevāya. Oṁ namo bhagavate vāsudevāya. [Devotees repeat] [break] ...hi—indeed; akarma-kṛt—without performing action.
[00:32] Translation: "O inhabitants of Vaikuṇṭha, you are sinless, but those within this material world are all karmīs, whether acting piously or impiously. Both kinds of action are possible for them because they are contaminated by the three modes of nature and must act accordingly. One who has accepted a material body cannot be inactive, and sinful action is inevitable for one acting under the modes of material nature. Therefore all the living entities within this material world are punishable." Prabhupāda: sambhavanti hi bhadrāṇi viparītāni cānaghāḥ kāriṇāṁ guṇa-saṅgo 'sti dehavān na hy akarma-kṛt [SB 6.1.44] This material world is karma-kṛt—you have to do something.
Kṛṣṇa has explained that "Without acting, you cannot even maintain your body and soul together." Śarīra-yātrāpi te na prasiddhyed akarmaṇaḥ. [Bg 3.8] If you become idle, then you cannot even maintain your body. That is the difference between civilized man and uncivilized man or developed country... [child cries] [aside:] Stop that. ...developed country and undeveloped country.
Just like America. This land was inhabited by the Red Indians. They could not do anything, but the Europeans, when they migrated, they made it so beautiful country. So karma-kṛt, one has to work.
This material world is so made. Tṛtīyā karma-saṅgā anyā śaktir īṣyate. [Viṣṇu Purāṇa 6.7.61(1)] In the Padma Purāṇa, Viṣṇu Purāṇa: parasya śaktir vividhaiva śrūyate [Cc Madhya 13.65, purport]. God's energy are varieties.
All those varieties are grouped into three divisions. Out of that... Three divisions means taṭasthā-śakti, antaraṅgā-śakti, cit-śakti. Taṭasthā-śakti and this external, or this karma-śakti.
The... Tṛtīyā śaktiḥ karma-saṅgā anyā. It is mentioned that the spiritual world is just manifestation of cit-śakti, and this material world is creation of material energy or karma-saṅgā, where everyone has to work. Without work, it is said, na hi suptasya siṁhasya praviśanti mukhe mṛgāḥ [Hitopadeśa].
