Arjuna said: Who is best situated in yoga – those who constantly glorify You or those who are situated in Your impersonal, imperishable aspect?
Bhagavad Gita - Chapter 12 - Bhakti Yoga - The Yoga of Devotion
Bhagavan Shri Krishna replied: Those who fix their minds upon Me, who constantly glorify Me and possess great faith – I consider them to be most perfect.
However, those that control their senses, who are mentally composed in all situations, who are dedicated to helping all living beings and who worship My unfathomable, impersonal, inconceivable, unchanging, all-pervading aspect which is fixed and immovable – they also reach Me.
There is great difficulty for those whose minds are attached to the impersonal aspect. To progress on that path is most troublesome for embodied beings.
O Partha, those who renounce all actions and offer them to Me, who take shelter in Me, who are fully absorbed in meditating upon achieving My association and who always worship Me – I swiftly deliver them from the ocean of birth and death.
Fix your mind and intelligence on Me alone and ultimately you will come to Me. Of this there is no doubt.
Dhananjaya, if you cannot firmly fix your mind upon Me, then try to reach Me by the constant practice of bhakti-yoga.
If you cannot keep up the practices of bhakti-yoga, then just try offering your work to Me. Thus, you will reach the perfect stage.
If you are unable to do that, then do your work and offer the results to Me. While controlling the mind, give up all the results of your activities.
If you cannot follow this instruction then engage yourself in the cultivation of knowledge. However, meditation is superior to knowledge. Better than meditation is the renunciation of material gain, for by such renunciation one finds peace.
