Kula-dharma means if you are a brāhmaṇa, you must observe the regulative principles, the qualitative principles of a brāhmaṇa.
(Lecture on Bhagavad-Gita--1:37-39).

jāti-dharma means the family tradition that has got different types of responsibilities.
(Lecture on Bhagavad-Gita---1:41-42).

(Lecture on Srimad Bhagavatam--1:1:19).

Mānava-dharma means what Kṛṣṇa teaches—sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja. This is mānava-dharma. Except this, anything, that is paśu-dharma.
(Lecture on Bharatiya Vidya Bhavan).

Paśu-dharma means eating, sleeping, sexual intercourse, and defending.
(Lecture on Bharatiya Vidya Bhavan).

Scientific basis means it should be fact, not speculation, mano-dharma. Mano-dharma means speculation.
(Lecture on Bhagavad-Gita--16:7).

Sarva-dharma means this sva-dharma, jāti-dharma, or so many other dharmas man created for the nice keep-up of the society.

Any so-called religious system that is not in the line of devotional service is called adharma-saṁsthāpana.
(Srimad Bhagavatam----3:24:37----purport).

Here it is stated that the cause of devastation is Adharma, or Irreligion.
(Srimad Bhagavatam----4:8:5----purport).

It may be concluded that dharma, religion, refers to that which is ordered in the Vedas, and adharma, irreligion, refers to that which is not supported in the Vedas.
(Srimad Bhagavatam----6:1:40----purport).

If anyone actually wants relief, the best course is to surrender unto the Supreme Personality of Godhead. The Lord is also described here as sad-dharma-vidāṁ variṣṭham. This indicates that of all transcendental occupations the best occupation is eternal loving service unto the Supreme Personality of Godhead. Dharma is sometimes translated as "religion," but that is not exactly the meaning. Dharma actually means "that which one cannot give up," "that which is inseparable from oneself." The warmth of fire is inseparable from fire; therefore warmth is called the dharma, or nature, of fire. Similarly, sad-dharma means "eternal occupation." That eternal occupation is engagement in the transcendental loving service of the Lord.
(Srimad Bhagavatam----3:25:11----purport).

Sva means "own." Sva-dharmam: "one's own occupation." So according to Vedic civilization, everyone has his own sva-dharma. This has been misinterpreted by the rascals. Sva-dharma means anyone can discover his own religious principle. Yato mata tato patha. Whatever you think is religious principle, that's all right. This is going on. But that is not the meaning. Sva-dharma means "own occupation." Actually dharma means which you cannot give up. Dhṛ-dhātu. You have to capture it; to keep your existence you must capture it.
So because we have got body and soul, two different things, we are combination, body and soul. That is already explained very nicely in so many ways. So actually sva-dharma means the occupation of the soul. Because in the material condition we do not understand what I am—whether I am this body or I am soul. Mostly people they do not know that one is soul, not this body. Body is the dress or outward covering, external covering. Subtle covering and gross covering. But so long one is in the bodily concept of life, so one has got different occupational duty according to the conception of the body. So the nature is being conducted by three modes of nature. Therefore, according to one's nature there is occupational duty.
(Lecture on Bhagavad-Gita--2:31).

Sva-dharma means the division, kṣatriya division of the society. The brāhmaṇa division, the kṣatriya division, the vaiśya division and the śūdra division. Everything is required. It is not that śūdra is not required. Śūdra is required, but if you make propaganda simply to make people śūdras, then who will give direction? If there is no head, who will give the direction? So a kṣatriya, kṣatriya has got a very difficult task to see. Kṣatriya means government, the governing division. So the governing division has got a very important duty to see that everyone is following his duty. The brāhmaṇa is following his duty, a kṣatriya is following his duty, vaiśya is following the duty, and śūdra... That is, government's duty.
(Lecture on Bhagavad-Gita--2:31).

Sva-dharma means, you are in brahminical quality, your work is this. You are in martial spirit—one who is intelligent, for him, studying Vedas, understanding the philosophy, preaching for the good of the society, train them, guide them, this is brāhmaṇa's business. Brāhmaṇa is not going to work in the factory. That is not brāhmaṇa's business. But in modern civilization, everyone should go to factory. Never mind whether you are brāhmaṇa or śūdra or a... This is the mistake. Therefore, if I am not fit for a certain thing and if I am engaged in that business, that will be failure. That will be failure. For a particular type of business, occupation, one must have particular type of brain. So therefore this is division. Not that everyone is of the same type. You cannot find. There is not... Because the world is being conducted by the three modes of nature, you cannot find all men of the same category. There must be intelligent class of men, there must be martial spirit, administrative class of men, there must be business minded men. There must be śūdras, they do not know anything, they want to serve only, master. So therefore, scientifically it is divided.
(Lecture on Bhagavad-Gita--2:40).

Dharma means the real occupation of the living entity.
(Srimad Bhagavatam----3:24:37----purport).

Sanātana means "eternal," and dharma means "occupational duties."
(Srimad Bhagavatam----8:14:4----purport).

The principles of Vaiṣṇavism are to satisfy the Lord by all means. A Vaiṣṇava is by nature a nonviolent, peaceful living being, and he has all the good qualities of God, but when the nondevotee blasphemes the Lord or His devotee, the Vaiṣṇava never tolerates such impudency.
After this incident the Lord began to preach and propagate His Bhāgavata-dharma, or saṅkīrtana movement, more vigorously, and whoever stood against this propagation of the yuga-dharma, or duty of the age, was properly punished by various types of chastisement.
(Srimad Bhagavatam--introduction).
