Routine work performed as an obligation in terms of the scriptural injunctions, without desire for results, is action in the mode of goodness.
(Bhagavad-Gita----2:47----purport).

If in one's present life one lives in the mode of goodness and always thinks of Kṛṣṇa, it is possible for one to remember Kṛṣṇa at the end of one's life.
(Bhagavad-Gita----8:6----purport).

Everything done in the mode of goodness does advance one, however, and fasting done in terms of the Vedic injunctions enriches one in spiritual knowledge.
(Bhagavad-Gita----10:4-5----purport).

The living entities conditioned by material nature are of various types. One is happy, another is very active, and another is helpless. All these types of psychological manifestations are causes of the entities' conditioned status in nature. How they are differently conditioned is explained in this section of Bhagavad-gītā. The mode of goodness is first considered. The effect of developing the mode of goodness in the material world is that one becomes wiser than those otherwise conditioned. A man in the mode of goodness is not so much affected by material miseries, and he has a sense of advancement in material knowledge. The representative type is the brāhmaṇa, who is supposed to be situated in the mode of goodness. This sense of happiness is due to understanding that, in the mode of goodness, one is more or less free from sinful reactions. Actually, in the Vedic literature it is said that themode of goodness means greater knowledge and a greater sense of happiness.
(Bhagavad-Gita----14:6----purport).

A person in the mode of goodness is satisfied by his work or intellectual pursuit, just as a philosopher, scientist or educator may be engaged in a particular field of knowledge and may be satisfied in that way.
(Bhagavad-Gita----14:9----purport).

When one dies in the mode of goodness, he attains to the pure higher planets of the great sages.
(Bhagavad-Gita----14:14----translation).

The result of pious activities in the mode of goodness is pure.
(Bhagavad-Gita----14:16----purport).

Now, according to Vedic rites, activities in the mode of goodness are considered auspicious for progress on the path of liberation, and such activities are known as daivī prakṛti, transcendental by nature.
(Bhagavad-Gita----16:1-3----purport).

Śraddhā, or faith, originally comes out of the mode of goodness.
(Bhagavad-Gita----17:3----purport).

Charity given out of duty, without expectation of return, at the proper time and place, and to a worthy person is considered to be in the mode of goodness.
(Bhagavad-Gita----17:20----translation).

That knowledge by which one undivided spiritual nature is seen in all living entities, though they are divided into innumerable forms, you should understand to be in the mode of goodness.
(Bhagavad-Gita----18:20----purport).

That action which is regulated and which is performed without attachment, without love or hatred, and without desire for fruitive results is said to be in the mode of goodness.
(Bhagavad-Gita----18:23----translation).

One who performs his duty without association with the modes of material nature, without false ego, with great determination and enthusiasm, and without wavering in success or failure is said to be a worker in the mode of goodness.
(Bhagavad-Gita----18:26----translation).

A person in Kṛṣṇa consciousness is always transcendental to the material modes of nature. He has no expectations for the result of the work entrusted to him, because he is above false ego and pride. Still, he is always enthusiastic till the completion of such work. He does not worry about the distress undertaken; he is always enthusiastic. He does not care for success or failure; he is equal in both distress and happiness. Such a worker is situated in the mode of goodness.
(Bhagavad-Gita----18:26----purport).

O son of Pṛthā, that determination which is unbreakable, which is sustained with steadfastness by yoga practice, and which thus controls the activities of the mind, life and senses is determination in the mode of goodness.

That which in the beginning may be just like poison but at the end is just like nectar and which awakens one to self-realization is said to be happiness in the mode of goodness.
(Bhagavad-Gita----18:37----translation).
