The resolute purpose of a person in Kṛṣṇa consciousness is based on knowledge. Vāsudevaḥ sarvam iti sa mahātmā su-durlabhaḥ: a person in Kṛṣṇa consciousness is the rare good soul who knows perfectly that Vāsudeva, or Kṛṣṇa, is the root of all manifested causes. As by watering the root of a tree one automatically distributes water to the leaves and branches, so by acting in Kṛṣṇa consciousness one can render the highest service to everyone—namely self, family, society, country, humanity, etc. If Kṛṣṇa is satisfied by one's actions, then everyone will be satisfied.
(Bhagavad-Gita---2:41---purport).

(Bhagavad-Gita---3:9---purport).

The duality of the material world is felt in terms of heat and cold, or misery and happiness. A Kṛṣṇa conscious person is above duality because he does not hesitate to act in any way for the satisfaction of Kṛṣṇa. Therefore he is steady both in success and in failure. These signs are visible when one is fully in transcendental knowledge.
(Bhagavad-Gita---4:22---purport).

(Srimad Bhagavatam---7:5:23-24---purport).

A person who has attained the paramahaṁsa stage knows very well the distinction between matter and spirit. He is not at all interested in gratifying the material senses, for he is always deriving pleasure from devotional service to the Lord. He is not very anxious to protect his material body. Being satisfied with whatever he attains by the grace of the Lord, he is completely independent of material happiness and distress, and thus he is transcendental to all regulative principles. Sometimes he accepts severe austerities, and sometimes he accepts material opulence. His only concern is to satisfy Kṛṣṇa, and for that purpose he can do anything and everything, without reference to the regulative principles. He is never to be equated with materialistic men, nor is he subject to the judgments of such men.

(Sri Caitanya Caritamrta---2:19:167---purport).

If we are actually surrendered to the lotus feet of Kṛṣṇa, our only desire should be to satisfy Kṛṣṇa. That is pure Kṛṣṇa consciousness.

The body of a karmī is called material because the karmī, being too absorbed in material activities, is always eager to enjoy material facilities, but the body of a devotee who tries his best to work very hard for the satisfaction of Kṛṣṇa by fully engaging in the Lord's service must be accepted as transcendental.
(Sri Caitanya Caritamrta---3:4:173---purport).
