The four internal subtle senses and their relationship

From Text SB 3.26.14

mano buddhir ahaṅkāraś  cittam ity antar-ātmakam
caturdhā lakṣyate bhedo  vṛttyā lakṣaṇa-rūpayā

Word for word: 

manaḥ — the mind; buddhiḥ — intelligence; ahaṅkāraḥ — ego; cittam — consciousness; iti — thus; antaḥ-ātmakam — the internal, subtle senses; catuḥ-dhā — having four aspects; lakṣyate — is observed; bhedaḥ — the distinction; vṛttyā — by their functions; lakṣaṇa-rūpayā — representing different characteristics.

Translation: 

The internal, subtle senses are experienced as having four aspects, in the shape of mind, intelligence, ego and contaminated consciousness. Distinctions between them can be made only by different functions, since they represent different characteristics.

The four internal subtle senses as explained in Text 14 are:

1. citta - a sense of awareness or consciousness
2. ahankara- a false sense of self ,false ego
3. manah- the accepting and rejecting function known as the mind
4. buddhih- the discriminating function known as the intelligence

Percieving the Lord through intelligence

From SB 2.2.35:
Translation:
The Personality of Godhead Lord Śrī Kṛṣṇa is in every living being along with the individual soul. And this fact is perceived and hypothesized in our acts of seeing and taking help from the intelligence.

Srila Prabhupada's purport explains this aspect.

Intelligent persons abandon everything else to obtain the Supreme Personality of Godhead

Rukmini uvaca from the chapter Krsna teases Rukmini:

SB 10.60.38: You are the embodiment of all human goals and are Yourself the final aim of life. Desiring to attain You, O all-powerful Lord, intelligent persons abandon everything else. It is they who are worthy of Your association, not men and women absorbed in the pleasure and grief resulting from their mutual lust.

From the purport:

"In fact, only those who have given up all such material conceptions of sense gratification and have taken exclusively to the Lord's loving service can understand who their real friend and companion is — Lord Śrī Kṛṣṇa Himself."

Oh Lord help me follow in the footsteps of the intelligent persons mentioned her. Help me give up my attachments , help me give up my mundane expectations from people and relatives - those bind me down and block me in furthering my relationship withYou

Help me overcome bad habits that drive me to mundane sense gratification like the internet, like the dirty joy derived from gossip and criticism of devotees. I do not wish to be blocked by these in getting closer to You and serving You.

Please lift me from my past conditioning and habits that block me from performing unmotivated uninterrupted service to You. I wish to serve You and Your devotees , please help me to give myself exclusively to You.

Those fixed in devotion do not have material desires

SB 10.22.26: The desire of those who fix their minds on Me does not lead to material desire for sense gratification, just as barleycorns burned by the sun and then cooked can no longer grow into new sprouts.

The words mayy āveśita-dhiyām are very significant here. Unless one has achieved an advanced degree of devotion, one cannot fix the mind and intelligence on Kṛṣṇa, since Kṛṣṇa is pure spiritual existence. Self-realization is a state not of desirelessness but rather of purified desire, wherein one desires only the pleasure of Lord Kṛṣṇa. The gopīs were certainly attracted to Kṛṣṇa in a mood of conjugal love, and yet, having fixed their minds and indeed their entire existence completely on Kṛṣṇa, their conjugal desire could never manifest as material lust; rather, it became the most exalted form of love of Godhead ever seen within the universe.
