Let us journey through the teachings of the Bhagavad Gita, where Krishna describes to Arjuna the nature and path of the yogi. The true yogi is one whose mind is fulfilled by knowledge and wisdom, who remains steadfast and has conquered his senses. Such a person regards earth, stone, and gold with equal vision, unperturbed by their differences. He extends this equality of understanding to all: friends and companions, enemies and neutrals, mediators and those who hate, relatives, the virtuous and the sinful alike. This impartiality marks him as distinguished. Krishna instructs that the yogi should always practice self-union, seeking solitude, with a controlled mind and self, free from desires and possessions. In a clean place, he should prepare a firm seat—neither too high nor too low—using cloth, deer skin, and kusa grass as its base. There, with senses and thoughts controlled, he sits, making his mind one-pointed, and practices yoga for self-purification. The yogi holds his body, head, and neck straight and steady, gazing at the tip of his own nose, without letting his eyes wander. With a peaceful mind, free from fear, established in the vow of celibacy, he sits, controlling his mind, absorbed in Krishna, devoted wholly to Him. By always practicing self-union in this way, with a controlled mind, the yogi attains peace—supreme liberation—established in Krishna. Yet, Krishna cautions that yoga is not for one who eats too much, nor for one who abstains entirely; nor for one who sleeps excessively, nor for one who is always awake. For the one who is moderate in eating and recreation, moderate in actions, moderate in sleep and waking, yoga destroys all suffering. When the mind is controlled and rests only in the self, free from all desires, then one is said to be truly united in yoga. Like a lamp in a windless place, which does not flicker, so is the yogi whose mind is controlled and who practices self-union. When, through yoga, the mind is restrained and comes to rest, and when, seeing the self by the self, one is content within, there arises a happiness that is boundless, grasped by the intellect and beyond the senses. Established in that state, one does not waver from truth. Having attained this, nothing else is considered a greater gain; and even great sorrow cannot shake one from it. This, Krishna says, is yoga—disconnection from union with suffering. It must be practiced with determination and an unwavering mind. One must abandon all desires born of intention and restrain the senses on all sides by the mind alone. Gradually, step by step, one should attain stillness, holding the intellect steady, fixing the mind on the self, thinking of nothing else. Whenever the restless mind wanders, one should restrain it and bring it under the control of the self. Supreme happiness comes to the yogi whose mind is peaceful, whose passions are calmed, who has become Brahman, and is free from blemish. Constantly disciplining himself in this way, the yogi, freed from impurities, easily attains boundless happiness through contact with Brahman. With the mind united in yoga, the yogi sees the self abiding in all beings and all beings in the self, viewing everything with equal vision. He who sees Krishna everywhere and sees everything in Krishna is never lost to Krishna, nor is Krishna lost to him. He who worships Krishna, established in unity, abiding in all beings, lives in Krishna, whatever his way of life. The yogi who, by comparison with himself, sees the same everywhere—in happiness or in sorrow—is considered supreme. Arjuna, hearing this, speaks: "O Madhusudana, this yoga of equanimity which you describe, I do not see a steady foundation for it, because the mind is so restless." He says, "The mind is restless, turbulent, strong, and obstinate; controlling it is as difficult as controlling the wind." Krishna replies gently: "Without doubt, O mighty-armed, the mind is hard to control and restless, but by practice and detachment, O son of Kunti, it can be restrained. In my view, yoga is difficult to attain for one whose self is not controlled; but for one who has mastered the self and strives by proper means, it is attainable." Arjuna asks further: "What is the fate, O Krishna, of one who, though endowed with faith, but lacking self-control, whose mind strays from yoga and does not attain perfection? Does one who has fallen from both paths perish like a broken cloud, lost and without foundation, confused on the path to Brahman? This is my doubt, Krishna; you alone can resolve it completely." Krishna reassures him: "O Partha, neither here nor hereafter is there destruction for him. Surely, one who acts virtuously never comes to misfortune, dear one. Having attained the worlds of the righteous and dwelled there for many ages, the one fallen from yoga is born in the home of the pure and prosperous. Or else, he is born in the family of wise yogis. Such a birth is indeed rare in this world." "There, he obtains the connection with the intellect from his previous body, and strives again for perfection, O descendant of Kuru. By that former practice, he is drawn even against his will. Even one who desires to know yoga transcends the words of scripture. But the yogi, striving with effort, purified from faults, perfected through many births, attains the highest path." Krishna declares, "The yogi is greater than ascetics, greater even than the wise, and greater than those who act. Therefore, become a yogi, Arjuna. Among all yogis, the one who worships Me with faith, with his inner self absorbed in Me, is considered by Me to be the most united." Thus, Krishna reveals the path of yoga—its discipline, its challenges, and its supreme rewards—guiding Arjuna to become a yogi devoted to Him, established in unity and compassion.
