On sva-dharma

From the purport to the verse: SB 4.24.53

My dear Lord, those who desire to purify their existence must always engage in meditation upon Your lotus feet, as described above. Those who are serious about executing their occupational duties and who want freedom from fear must take to this process of bhakti-yoga.

The word sva-dharmam (as in sva-dharmam anutiṣṭhatām) indicates that the system of varṇāśrama — which indicates the occupational duties of the brāhmaṇa, kṣatriya, vaiśya and śūdra and which is the perfect institution for humanity — must be supported by bhakti-yoga if one at all wants security in life. Generally people think that simply by executing the occupational duties of a brāhmaṇa, kṣatriya, vaiśya or śūdra or the duty of a brahmacārī, gṛhastha, vānaprastha or sannyāsī one becomes fearless or securely attains liberation, but factually unless all these occupational duties are accompanied by bhakti-yoga, one cannot become fearless. In Bhagavad-gītā there are descriptions of karma-yoga, jñāna-yoga, bhakti-yoga, dhyāna-yoga, etc., but unless one comes to the point ofbhakti-yoga, these other yogas cannot help one attain the highest perfection of life. In other words, bhakti-yoga is the only means for liberation. We find this conclusion also in Caitanya-caritāmṛta in a discussion between Lord Caitanya and Rāmānanda Rāya regarding a human being’s liberation from this material world. In that discussion Rāmānanda Rāya referred to the execution of varṇāśrama-dharma, and Lord Caitanya indicated that thevarṇāśrama-dharma was simply external (eho bāhya). Lord Caitanya wanted to impress upon Rāmānanda Rāya that simply by executing the duties of varṇāśrama-dharma one is not guaranteed liberation. Finally Rāmānanda Rāya referred to the process of bhakti-yoga: sthāne sthitāḥ śruti-gatāṁ tanu-vāṅ-manobhiḥ (Bhāg. 10.14.3). Regardless of one’s condition of life, if he practices bhakti-yoga, which begins with hearing (śruti-gatām) the transcendental messages of the Lord through the mouths of devotees, he gradually conquers the unconquerable God.

God is known to be unconquerable, but one who submissively hears the words of a self-realized soul conquers the unconquerable. The conclusion is that if one is serious about liberation, he not only should execute the occupational duties of varṇāśrama-dharma but should also engage in bhakti-yoga by beginning hearing from a realized soul. This process will help the devotee conquer the unconquerable Supreme Personality of Godhead and become His associate after giving up the material body.
