ध्यानयोगः — Dhyāna-Yoga
Discipline of Meditation and Mental Restraint
न हि ज्ञानेन सदृशं पवित्रमिह विद्यते । तत् स्वयं योगसंसिद्ध: कालेनात्मनि विन्दति,इस संसारमें ज्ञानके समान पवित्र करनेवाला निःसंदेह कुछ भी नहीं है। उस ज्ञानको कितने ही कालसे कर्मयोगके द्वारा शुद्धान्त:करण हुआ मनुष्य अपने- आप ही आत्मामें पा लेता है:
na hi jñānena sadṛśaṃ pavitram iha vidyate | tat svayaṃ yogasaṃsiddhaḥ kālenātmani vindati ||
For in this world there is nothing as purifying as knowledge. That knowledge, in due course, is found within the Self by one who has been perfected through yoga—whose inner being has been refined by disciplined action and steady practice.
अजुन उवाच
Knowledge (jñāna) is presented as the supreme purifier. When a person becomes mature through yoga—especially disciplined, selfless practice that refines the mind—this knowledge is not merely learned externally but is realized inwardly, in the Self, in due time.
In the midst of the battlefield instruction, the teaching turns to inner discipline: the speaker emphasizes that spiritual purity and clarity arise most powerfully from true knowledge, which dawns naturally within one who has steadily cultivated yogic maturity over time.
