Some mentalities like the one mentioned in this section(page 71 of the PDF document) of the Laghu Yoga Vasiṣṭha set in stably only when the vāsanās favourable to generating that state of mind set in. They can be generated in various ways,like:
- This meditation on various parts of the body(pages 44 to 50 of the document)(after completing the preliminaries to do that sort of meditation) in the Nāstika Theravāda tradition
- Bhagavad Nāmasmaraṇa(after leading a life with moderation and control in senses)(uninterrupted rememberance/repitition of the names of various deities like Viṣṇu,Kṛṣṇa,Śiva,etc). In this light,the advice of Rūpa Gosvāmīn in the Upadeśāmṛta is helpful(quoting from Prabhupada’s translation)
vāco vegaṁ manasaḥ krodha-vegaṁ
etān vegān yo viṣaheta dhīraḥ
sarvām apīmāṁ pṛthivīṁ sa śiṣyāt
A sober person who can tolerate the urge to speak, the mind’s demands, the actions of anger and the urges of the tongue, belly and genitals is qualified to make disciples all over the world.
atyāhāraḥ prayāsaś ca
jana-saṅgaś ca laulyaṁ ca
ṣaḍbhir bhaktir vinaśyati
One’s devotional service is spoiled when he becomes too entangled in the following six activities: (1) eating more than necessary or collecting more funds than required; (2) overendeavoring for mundane things that are very difficult to obtain; (3) talking unnecessarily about mundane subject matters; (4) Practicing the scriptural rules and regulations only for the sake of following them and not for the sake of spiritual advancement, or rejecting the rules and regulations of the scriptures and working independently or whimsically; (5) associating with worldly-minded persons who are not interested in devotionalism; and (6) being greedy for mundane achievements.
utsāhān niścayād dhairyāt
saṅga-tyāgāt sato vṛtteḥ
ṣaḍbhir bhaktiḥ prasidhyati
There are six principles favorable to the execution of pure devotional service: (1) being enthusiastic, (2) endeavoring with confidence, (3) being patient, (4) acting according to regulative principles [such as śravaṇaṁ kīrtanaṁ
7.5.23]—hearing, chanting and remembering Kṛṣṇa
], (5) abandoning the association of nondevotees, and (6) following in the footsteps of the previous ācāryas. These six principles undoubtedly assure the complete success of pure devotional service.
Of course in the course of practicing devotional service as mentioned above,that vāsanā automatically sets in as a consequence of the bhava towards the deity.
So,insights like these are of a ‘yogic’ class,and do not remain stable/hardly arise in one who is not inclined to any form of yoga(hence,the reason you don’t find many anatomy students/professors becoming renunciants),and have to be cultivated and strengthened as we practice yoga.
