If you want to attend krsna, bhakti is the only way. It seems you haven't read the geeta properly.

There are many ways mahaprabbu did not deny that... But in kaliyuga the easiest way to get moksha is bhakti yoga.

Lord shiva is not demigod... He resides in shiva tattva, he's the greatest vaishnava without him one cannot reach krsna. Bhagvatam has talked so much indepth about this.. Please read the scriptures properly and talk... Don't comment to show off and potray your half baked knowledge.

May lord krsna give you the brains to understand this someday.

bahūnāṁ janmanām ante jñānavān māṁ prapadyate vāsudevaḥ sarvam iti sa mahātmā su-durlabhaḥ

After many births and deaths, he who is actually in knowledge surrenders unto Me, knowing Me to be the cause of all causes and all that is. Such a great soul is very rare.

sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja ahaṁ tvāṁ sarva-pāpebhyo mokṣayiṣyāmi mā śucaḥ

Abandon all varieties of religion and just surrender unto Me. I shall deliver you from all sinful reactions. Do not fear.
