While getting initiation under an authorized sampradaya is a very high achievement, it also comes with several rules and regulations one needs to follow carefully.
Following is from a segment from Srila Prabhupada:
When the disciple is qualified, the guru will appear and all that is knowable will automatically be known to the disciple.
yasya deve parā bhaktir yathā deve tathā gurau
tasyaite kathitā hy arthāḥ prakāśante mahātmanaḥ
“Only unto those great souls who have implicit faith in both the Lord and the spiritual master are all the imports of Vedic knowledge automatically revealed.”
(Śvetāśvatara Upaniṣad 6.23)
To have realized the eternal rasa and status of one’s guru, or one’s own eternal rasa with Kṛṣṇa, is certainly an exalted state of Kṛṣṇa consciousness, and with certainty one can say that such realizations are an intimate part of one’s bhajana. According to the core Gauḍīya Vaiṣṇava scriptures composed by Sanātana Gosvāmī, Jīva Gosvāmī and Narrottama Dāsa Ṭhākura, such intimacies are better kept secret — not to be told here and there for the public ears, and certainly not to be forced upon others.
gopayed devatām iṣṭāṁ
gopayed gurum ātmanaḥ
gopayec ca nijaṁ mantra
gopayen nija-mālikām
“One should hide one’s worshippable Deity, one should hide one’s guru, one should hide one’s mantra, and one should hide one’s japa–mālā.” (Sanātana Gosvāmī, Hari-bhakti-vilāsa 2.147)
atra ca śrī-guroḥ śrī-bhagavato vā
prasāda-labdhaṁ sādhana-sādhya-gataṁ
sīéya-sarvasva-bhūtaṁ yat kim api rahasyaṁ,
tat tu na kasmaicit prakāśanīyam
“Whatever confidential experiences are obtained in connection with ones sādhana and the goal awarded by the mercy of Śrī Guru or the Lord, that is one’s own wealth and should not be revealed to anyone.” (Jīva Gosvāmī, Bhakti Sandarbha 339)
āpana bhajana kathā,
nā kahibo yathā tathā
ihāte haiba sāvadhāna
“I will be careful not to reveal my own bhajana here and there.” (Narottama Dāsa Ṭhākura, Prema-bhakti-candrikā 119)
So, in summary:
1) Hide your beloved deity (ishta deva) in your heart
2) Hide your guru in your heart
3) Hide your mantra (so that no one can hear from you)
4) Hide your mālā (this is why we chant in a bead bag)
If we follow these, spiritual advancement will surely be faster.
