In Sanskrit:
न हि ज्ञानेन सदृशं पवित्रमिह विद्यते।
तत्स्वयं योगसंसिद्धः कालेनात्मनि विन्दति॥
na hi jñānena sadṛśaṃ pavitramiha vidyate
tatsvayaṃ yogasaṃsiddhaḥ kālenātmani vindati
Translation (Meaning in English):
In this world, there is nothing so purifying as knowledge. One who has attained perfection in yoga, finds it within himself in due course of time.
Lessons:
As one of the best slokas from Bhagavad Gita, it teaches us that knowledge is the most powerful tool for purifying oneself. It is through knowledge that one can overcome ignorance and attain enlightenment.
Yoga is a means to attain knowledge and self-realization. Through the practice of yoga, one can achieve a state of union with the divine and discover the true nature of the self.
It also tells us that the path to self-realization is not easy and requires time, effort, and dedication.
It is a gradual process that requires patience and perseverance. Moreover, self-realization is not something that can be attained through external means. It is a journey of self-discovery that takes place within oneself.
