There are some essential requisites of devotion which are as follows –
- Devotion to the supreme with an undivided mind.
- Complete indifference to all dualities such as good and evil, friend and foe, honor and ignominy, heat and cold, pleasure and pain, etc.
- Perfect control over the mind and the senses.
- Absence of attachment or malice towards all beings.
- Complete surrender at the feet of Bhagavan - total surrender of ego.
Bhagavan Sri Krishna accepts to teach Arjuna when the latter
surrenders himself at his feet (Bhagavad Gita Chapter II.7). Whoever surrenders
at the feet of Ishwara, abandoning all attachments of worldly life, is absolved
of all impressions in the inner self caused by wrong acts (XVIII.66). Those who
have their wisdom carried away by nescience and who have embraced the demoniac nature,
such foolish and wretched persons of evil deeds do not seek refuge in Him
(VII.15).
