Swami Parthasarthy shared some interesting points on the the paths advocated in Hinduism.
1) Devotion/Bhakti/Unconditional Love
Since the day you were born, you were taken care of. Nutrition/Milk was magically produced for you...oxygen was provided free for you to breathe...If you bruise yourself, forces come out to heal...
Surrender to 'What is'
That is Bhakti
When you are ill, you surrender to a doctor
Similarly, you surrender to a lawyer, a pilot...

2) Knowledge, Gyaan is to know what is permanent and impermanent.
Chinta taaki kijiye jo anhonne hoi
means
Worry about that which is permanent (God, spiritual matters)
Constant awareness of what is 'Nitya' and 'Anitya'
