Purport

As stated in earlier Shloka, all Yajnas are liberating for a human being, but still, there are some Yajnas which are better than others. In this Shloka Bhagvan Shri Krishna explains the same by classifying all Yajnas into two parts.

1. Sacrifice(Yajna) of Wisdom and
2. Material Sacrifice

Bhagvan declares that all Yajnas which are done for the wisdom are better than the material sacrifice(Yajna). Explaining the reasons, Shri Krishna further explained that wisdom is the final result of all actions.

If we want to put a different type of Yajnas in the above categories, we might place as follows:

Jnana yajna(sacrifice of wisdom)
Bramha Yajna(The devotion)
Yoga of mind(Raj yoga)
Pranayam (Yoga of breaths)
Acquiring and distributing knowledge
Tapasya (Renunciation of worldly desires)

Material Sacrifice
Deva Yajna(Worship of deities)
Charity(Dana)
Steadfast
Self-control

Yoga of physical control(Hatha Yoga like Asana)

Yajnas of the first type are better than the second type.
