Chapter Ten: The Opulence of the Absolute.

All wondrous phenomena showing power, beauty, grandeur or sublimity, either in the material world or in the spiritual, are but partial manifestations of Krishna's divine energies and opulence. As the supreme cause of all causes and the support and essence of everything, Krishna is the supreme object of worship for all beings.

Chapter Eleven: The Universal Form.

Lord Krishna grants Arjuna divine vision and reveals His spectacular unlimited form as the cosmic universe. Thus He conclusively establishes His divinity. Krishna explains that His own all-beautiful humanlike form is the original form of Godhead. One can perceive this form only by pure devotional service.

Chapter Twelve: Devotional Service (Bhakti-yoga).

Bhakti-yoga, pure devotional service to Lord Krishna, is the highest and most expedient means for attaining pure love for Krishna, which is the highest end of spiritual existence. Those who follow this supreme path develop divine qualities.
