In my humble opinion, I do not think thirst for knowledge is any hindrance in the sound current path.
Rather, if there is any hindrrance it is the desire of possesing or aquiring to dominate or boast about it, this in reality is hankar or ego, and ego is the last vikaar/thief to leave .
The example I usually give for the above situation is that one of Ravan.
What jap or tap did he not perform? Then too, he was yet very much wicked even after aquiring so many powers, that he had overpowered the devtays and all the 5 chor were very much active in him, that too being such a devotee of the god Shiva.
Though bhakti is performed by almost everybody in all the religions, but there is definetely difference of whom the bhakti is done of.
Like the one of worshipping the numerous deities, trinties, or gods on one side, or, worshipping the Highest Truth, which is infinite, eternal and changeless, namely Waheguru Akal Purukh/Satnam/Nam or Shabad.
We are extremely lucky that we are born in sikh dharam, that due to His grace, that we by devoting ourselves to Him Waheguru Akal Purukh, we for sure reach His abode safely and totally pure, for engaging in His bhakti, we graduallly become pure/paviter, desireless, humble, full in faith and love for His Lotus Feet....
Even our chains from the never ending cycle of births and deaths are cut off, we have no more accounts to be settled with Dharam Raj .
To get the most(Him), by giving just a little bit of ourselves(manmukhta) regularly.
Isn´t it incredible? Isn´t it amazing? So much grace, so much mercy, on us sinners.
What else can one want ?
To love Him, we do not have to go anywhere, nor do any penances, or leave home or family, neither endure hardships on the physical body, but simply sit at one place, close the eyes and concentrate to meditate on Him.
That´s it, as simple as that.
In this respect, the Bani beautifully and in simple words tells us:
Prabh ka simran mun kee mael jaae. ( By His simran, all vikars, sins, pollution on the mind, are washed away)
Prabh ka simran garb na baseh. ( By His simran, one is not born again in any joonee)
Jin Har japeeya, se Har hoeeya. ( He whosoever meditates on Him by His jaap, becomes Him)
His simran, as seen, is the only means to reach Him, not only that, but something still more wonderful, which is merging in Him and becoming Him.
Stay blessed.
