As per the Bhagwat Gita, devotion is the easiest method to know the truth about self knowledge / soul knowledge & get close to the God. God himself declares about the glory of devotion in Bhagwat Gita: Chapter Eighteen verse 65 & 66 which are here given below.
Bhagwat Gita: Chapter Eighteen verse 65:
"man-mana bhava mad-bhakto
mad-yaji mam namaskuru
mam evaishyasi satyam te
pratijane priyo ’si me" (Bhagwat Gita: Chapter Eighteen verse 65)
"Sri Krishna says to Arjuna: Always think of Me, become My devotee, worship Me and offer your homage unto Me. Thus you will come to Me without fail. I promise you this because you are My very dear friend."
Bhagwat Gita: Chapter Eighteen verse 66:
mam ekam saranam vraja
aham tvam sarva-papebhyo
mokshayisyami ma suchah" (Bhagwat Gita: Chapter Eighteen verse 66)
"Sri Krishna says to Arjuna: Abandon all varieties of religion and just surrender unto Me. I shall deliver you from all sinful reactions. Do not fear."
So lets have devotion in God.
