Desires and bodily sensations are a part of human existence as ṣaḍ-ripu (षड्-रिपु) & ṣaḍ-ūrmi (षड्-ऊर्मि), as I discuss here. And they're enemies (रिपु), not friends.
Catering to one's senses and desires is a bottomless pit. There is no end to desires and sense gratification.
- Manu Smrti 2.93 says adhering to desires is source of evil:-
इन्द्रियाणां प्रसङ्गेन दोषं ऋच्छत्यसंशयम् । संनियम्य तु तान्येव ततः
सिद्धिं निगच्छति ॥ ९३ ॥
By attachment to the organs one incurs evil, without doubt; while by subjugating those same he attains success.—(93)
- And such gratification only increases, with greed for more, and MORE!
न जातु कामः कामानामुपभोगेन शाम्यति । हविषा कृष्णवर्त्मैव भूय
एवाभिवर्धते ॥ ९४ ॥
Never is desire appeased by the enjoyment of desires; it only waxes
stronger, like fire by clarified butter.—(94)
To attain "grace", one has to become Stithaprajña, as I discuss about the concept in this answer. That's the summary of Chapter 2, which the OP quotes their question.
Only through slow subjugation and control of senses, following one's Dharma, step by step, does one become eligible to attain grace and liberation finally.
As Devī Bhāgavatapurāṇa proclaims in Chapter 1, Book 4:-
शूद्रः स्वधर्मनिष्ठस्तु देहान्ते क्षत्रियस्तु सः । शुभाचारो मृतो यो वै
स शूद्रो ब्राह्मणो भवेत् ॥ १८ ॥ ब्राह्मणो निःस्पृहः शान्तो
भवरोगाद्विमुच्यते । विपरीतमिदं भाति नरनारायणौ च तौ ॥ १९ ॥
- to 19. If any Śūdra dies performing his own religion, he takes up a
Vaiśya body in his next incarnation; if any Vaiśya died so, he takes
up a Kṣattriya body and a Kṣattriya when adhering to his own rites and
ceremonies, dying takes up a Brāhmaṇ body in his next incarnation. And
if a Brāhmin be free from desires and resorts to the path of peace,
when he dies, he becomes free from incarnations and is saved from this
disease of getting into the world.
So, constant sense gratification is not the way to achieve grace. Rather, only through slow subjugation of the senses over time, step - by-step, does one attains grace. Let thou NOT be controlled by desires, but thou should be in the control of them.
