This verse describes the practice of yogic concentration, emphasizing the control of the senses, mind, and life force to attain higher states of consciousness and spiritual realization. Krishna instructs to control all the gates of the body (sarvadvārāṇi saṁyamya). The gates of the body refer to the senses through which external stimuli are perceived. To practice yogic concentration effectively, one must regulate and restrain the senses from being scattered outwardly, diverting attention away from the inward journey of self-discovery and realization.

Next, Krishna advises fixing the mind in the heart (mano hṛdi nirudhya). This involves directing the attention and focus of the mind towards the heart centre, the seat of consciousness and spiritual intuition. By withdrawing the mind from external distractions and anchoring it in the heart, one cultivates inner stability, clarity, and introspection, essential for deepening meditation and attaining self-awareness.

Furthermore, Krishna instructs to engage the life air at the top of the head (mūrdhnyādhāyātmanaḥ prāṇam āsthito). This refers to the practice of pranayama, the regulation and control of the breath, which plays a crucial role in harnessing the life force (prana) and channelling it upward towards higher spiritual centres. By directing the breath towards the crown of the head, one activates the subtle energy centres (chakras) and facilitates the ascent of consciousness, leading to expanded awareness and spiritual awakening.

Overall, this verse outlines the key components of yogic concentration, emphasizing the integration of body, mind, and breath in the practice of meditation. By mastering the control of the senses, focusing the mind in the heart, and directing the life force upward, practitioners can enhance their capacity for deep concentration, inner absorption, and spiritual transformation.
