We have an intimate relationship with the Lord, and because we are all qualitatively one—the sanātana-dhāma, or sky, the sanātana Supreme Personality and the sanātana living entities—the whole purpose of Bhagavad-gītā is to revive our sanātana occupation, or sanātana-dharma, which is the eternal occupation of the living entity. We are temporarily engaged in different activities, but all of these activities can be purified when we give up all these temporary activities and take up the activities which are prescribed by the Supreme Lord. That is called our pure life.

Bhagavad-gita As It Is
BG Preface and Introduction
BG Introduction:
The Lord comes Himself in different incarnations, or He sends His confidential servants as sons or His associates or ācāryas to reclaim the conditioned souls. Therefore, sanātana-dharma does not refer to any sectarian process of religion. It is the eternal function of the eternal living entities in relationship with the eternal Supreme Lord. Sanātana-dharma refers, as stated previously, to the eternal occupation of the living entity. Śrīpāda Rāmānujācārya has explained the word sanātana as "that which has neither beginning nor end," so when we speak of sanātana-dharma, we must take it for granted on the authority of Śrīpāda Rāmānujācārya that it has neither beginning nor end.
BG Introduction:
The English world religion is a little different from sanātana-dharma. Religion conveys the idea of faith, and faith may change. One may have faith in a particular process, and he may change this faith and adopt another, but sanātana-dharma refers to that activity which cannot be changed. For instance, liquidity cannot be taken from water, nor can heat be taken from fire. Similarly, the eternal function of the eternal living entity cannot be taken from the living entity. Sanātana-dharma is eternally integral with the living entity. When we speak of sanātana-dharma, therefore, we must take it for granted on the authority of Śrīpāda Rāmānujācārya that it has neither beginning nor end. That which has neither end nor beginning must not be sectarian, for it cannot be limited by any boundaries.
BG Introduction:
Those belonging to some sectarian faith will wrongly consider that sanātana-dharma is also sectarian, but if we go deeply into the matter and consider it in the light of modern science, it is possible for us to see that sanātana-dharma is the business of all the people of the world—nay, of all the living entities of the universe.
BG Introduction:
Non-sanātana religious faith may have some beginning in the annals of human history, but there is no beginning to the history of sanātana-dharma, because it remains eternally with the living entities. Insofar as the living entities are concerned, the authoritative śāstras state that the living entity has neither birth nor death. In the Gītā it is stated that the living entity is never born and he never dies. He is eternal and indestructible, and he continues to live after the destruction of his temporary material body.
BG Introduction:
In reference to the concept of sanātana-dharma, we must try to understand the concept of religion from the Sanskrit root meaning of the word. Dharma refers to that which is constantly existing with a particular object. We conclude that there is heat and light along with the fire; without heat and light, there is no meaning to the word fire. Similarly, we must discover the essential part of the living being, that part which is his constant companion. That constant companion is his eternal quality, and that eternal quality is his eternal religion.
BG Introduction:
The capitalist serves the family, and the family serves the state in the terms of the eternal capacity of the eternal living being. In this way we can see that no living being is exempt from rendering service to other living beings, and therefore we can safely conclude that service is the constant companion of the living being and that the rendering of service is the eternal religion of the living being.
Yet man professes to belong to a particular type of faith with reference to particular time and circumstance and thus claims to be a Hindu, Muslim, Christian, Buddhist or an adherent of any other sect. Such designations are non-sanātana-dharma. A Hindu may change his faith to become a Muslim, or a Muslim may change his faith to become a Hindu, or a Christian may change his faith and so on. But in all circumstances the change of religious faith does not affect the eternal occupation of rendering service to others. The Hindu, Muslim or Christian in all circumstances is servant of someone. Thus, to profess a particular type of faith is not to profess one's sanātana-dharma. The rendering of service is sanātana-dharma.
BG Chapters 1 - 6
BG 1.42, Purport:
Community projects for the four orders of human society, combined with family welfare activities, as they are set forth by the institution of sanātana-dharma, or varṇāśrama-dharma, are designed to enable the human being to attain his ultimate salvation. Therefore, the breaking of the sanātana-dharma tradition by irresponsible leaders of society brings about chaos in that society, and consequently people forget the aim of life-Viṣṇu. Such leaders are called blind, and persons who follow such leaders are sure to be led into chaos.

SB Canto 1
SB 1.11.36, Purport:
The path of salvation or the path going back to Godhead always forbids the association of women, and the complete sanātana-dharma or varṇāśrama-dharma scheme forbids or restricts association with women. How, then, can one be accepted as the Supreme Personality of Godhead who is addicted to more than sixteen thousand wives? This question may be relevantly raised by inquisitive persons really anxious to know about the transcendental nature of the Supreme Lord.
SB 1.12.12, Purport:
Only by pious acts can one be allowed to get good wealth, good education and beautiful features. The saṁskāras of the school of sanātana-dharma (man's eternal engagement) are highly suitable for creating an atmosphere for taking advantage of good stellar influences, and therefore garbhādhāna-saṁskāra, or the first seedling purificatory process prescribed for the higher castes, is the beginning of all pious acts to receive a good pious and intelligent class of men in human society. There will be peace and prosperity in the world due to good and sane population only; there is hell and disturbance only because of the unwanted, insane populace addicted to sex indulgence.
SB 1.15.27, Purport:
In the Bhagavad-gītā the Lord and the living beings are both described as sanātana, or eternal, and the Lord's abode, far beyond the material sky, is also described as sanātana. The living being is invited to live in the sanātana existence of the Lord, and the process which can help a living being to approach the Lord's abode, where the liberated activity of the soul is exhibited, is called sanātana-dharma. One cannot, however, reach the eternal abode of the Lord without being free from the misconception of material identification, and the Bhagavad-gītā gives us the clue how to achieve this stage of perfection.
SB 1.15.45, Purport:
According to the principles of sanātana-dharma, one must retire from family life after half the duration of life is finished and must engage himself in self-realization. But the question of engaging oneself is not always decided. Sometimes retired men are bewildered about how to engage themselves for the last days of life. Here is a decision by authorities like the Pāṇḍavas. All of them engaged themselves in favorably culturing the devotional service of the Lord Śrī Kṛṣṇa, the Supreme Personality of Godhead.
SB 1.19.4, Purport:
The life of a human being is a chance to prepare oneself to go back to Godhead, or to get rid of the material existence, the repetition of birth and death. Thus in the system of varṇāśrama-dharma every man and woman is trained for this purpose. In other words, the system of varṇāśrama-dharma is known also as sanātana-dharma, or the eternal occupation. The system of varṇāśrama-dharma prepares a man for going back to Godhead, and thus a householder is ordered to go to the forest as vānaprastha to acquire complete knowledge and then to take sannyāsa prior to his inevitable death.
SB Canto 2
SB 2.1.15, Purport:
Death is nothing but sleeping for a few months in order to develop another term of bodily encagement, which we are awarded by the law of nature according to our aspiration. Therefore, one has only to change the aspiration during the course of this present body, and for this there is need of training in the current duration of human life. This training can be begun at any stage of life, or even a few seconds before death, but the usual procedure is for one to get the training from very early life, from the stage of brahmacarya, and gradually progress to the gṛhastha, vānaprastha and sannyāsa orders of life. The institution which gives such training is called varṇāśrama-dharma, or the system of sanātana-dharma, the best procedure for making the human life perfect. One is therefore required to give up the attachment to family or social or political life just at the age of fifty years, if not earlier, and the training in the vānaprastha and sannyāsa-āśramas is given for preparation of the next life.
