When an individual perceives the illumination of knowledge within the body, they should recognize it as a manifestation of the mode of goodness. Krishna employs the metaphor of illumination to convey the clarity and discernment that arise from the mode of goodness. Just as light dispels darkness, the mode of goodness illuminates the mind, enabling one to perceive truth, wisdom, and spiritual insight.

The term "sarvadvāreṣu dehe" refers to the body, which serves as the abode of consciousness and the locus of experiences. Krishna emphasizes that within this physical vessel, the light of knowledge (jñāna) emanates, signifying the presence of the mode of goodness.

The verse highlights the transformative power of knowledge in elevating consciousness and fostering spiritual growth. By cultivating wisdom and discernment, one transcends the influence of material desires and attachments, aligning themselves with the mode of goodness.

Moreover, Krishna's teachings underscore the importance of self-awareness and introspection in understanding one's spiritual disposition. When an individual recognizes the presence of knowledge and clarity within themselves, they come to realize their innate connection with the mode of goodness.

The verse serves as a guiding principle for seekers on the path of self-realization. It encourages the cultivation of virtuous qualities such as wisdom, compassion, and equanimity, which are characteristic of the mode of goodness.

In essence, this verse from the Bhagavad Gita elucidates the characteristics of the mode of goodness and its manifestation within the human body. It emphasizes the transformative power of knowledge in fostering spiritual growth and aligning one's consciousness with higher truths. Through self-awareness and the cultivation of wisdom, one can transcend the influence of material modes and attain spiritual liberation.
