vitṛṣṇayā dvandva-titikṣayā ca
sarvatra jantor vyasanāvagatyā
mad-deva-saṅgād guṇa-kīrtanān me
sac-chraddhayā brahmacaryeṇa śaśvad
asampramādena yamena vācām
liṅgaṁ vyapohet kuśalo ’ham-ākhyam
In these four verses, Ṛṣabhadeva tells His sons how they can be freed from the false identification arising from false ego and material conditional life. One gradually becomes liberated by practicing as mentioned above. All these prescribed methods enable one to give up the material body (liṅgaṁ vyapohet) and be situated in his original spiritual body. First of all one has to accept a bona fide spiritual master. This is advocated by Śrīla Rūpa Gosvāmī in his Bhakti-rasāmṛta-sindhu: śrī-guru-pādāśrayaḥ. To be freed from the entanglement of the material world, one has to approach a spiritual master. Tad-vijñānārthaṁ sa gurum evābhigacchet. By questioning the spiritual master and by serving him, one can advance in spiritual life. When one engages in devotional service, naturally the attraction for personal comfort — for eating, sleeping and dressing — is reduced. By associating with the devotee, a spiritual standard is maintained. The word mad-deva-saṅgāt is very important. There are many so-called religions devoted to the worship of various demigods, but here good association means association with one who simply accepts Kṛṣṇa as his worshipable Deity.
Another important item is dvandva-titikṣā. As long as one is situated in the material world, there must be pleasure and pain arising from the material body. As Kṛṣṇa advises in Bhagavad-gītā, tāṁs titikṣasva bhārata. One has to learn how to tolerate the temporary pains and pleasures of this material world. One must also be detached from his family and practice celibacy. Sex with one’s wife according to the scriptural injunctions is also accepted as brahmacarya (celibacy), but illicit sex is opposed to religious principles, and it hampers advancement in spiritual consciousness. Another important word is vijñāna-virājita. Everything should be done very scientifically and consciously. One should be a realized soul. In this way, one can give up the entanglement of material bondage.
As Śrī Madhvācārya points out, the sum and substance of these four ślokas is that one should refrain from acting out of a desire for sense gratification and should instead always engage in the Lord’s loving service. In other words, bhakti-yoga is the acknowledged path of liberation. Śrīla Madhvācārya quotes from the Adhyātma:
ātmano ’vihitaṁ karma
kāmasya ca parityāgo
nirīhety āhur uttamāḥ
One should perform activities only for the benefit of the soul; any other activity should be given up. When a person is situated in this way, he is said to be desireless. Actually a living entity cannot be totally desireless, but when he desires the benefit of the soul and nothing else, he is said to be desireless.
Spiritual knowledge is jñāna-vijñāna-samanvitam. When one is fully equipped with jñāna and vijñāna, he is perfect. Jñāna means that one understands the Supreme Personality of Godhead, Viṣṇu, to be the Supreme Being. Vijñāna refers to the activities that liberate one from the ignorance of material existence. As stated in Śrīmad-Bhāgavatam (2.9.31): jñānaṁ parama-guhyaṁ me yad vijñāna-samanvitam. Knowledge of the Supreme Lord is very confidential, and the supreme knowledge by which one understands Him furthers the liberation of all living entities. This knowledge is vijñāna. As confirmed in Bhagavad-gītā (4.9):
janma karma ca me divyam
evaṁ yo vetti tattvataḥ
tyaktvā dehaṁ punar janma
naiti mām eti so ’rjuna
“One who knows the transcendental nature of My appearance and activities does not, upon leaving the body, take his birth again in this material world, but attains My eternal abode, O Arjuna.”
