Om Swami
Why don't I feel deep love for God right away, and is that a problem?
Devotion grows slowly, not overnight
With your deity, love grows on you gradually over a period of time; it doesn't happen overnight. If it happens overnight, it is usually a red flag.
With your deity, over a period of time, it gradually grows on you; you steadily fall in love with the divine. It doesn't happen overnight.
