Bhagavad Gita · Chapter 6: The Path of Meditation
Bhagavad Gita 6.36
असंयतात्मना योगो दुष्प्राप इति मे मतिः ।
वश्यात्मना तु यतता शक्योऽवाप्तुमुपायतः ॥
asaṃyatātmanā yogo duṣprāpa iti me matiḥ | vaśyātmanā tu yatatā śakyo'vāptumupāyataḥ ||
Yoga is hard to attain for one whose self is uncontrolled; that is my view. But one who is self-controlled and keeps striving can attain it by the right means.
Modern context
Krishna gives a balanced verdict. For someone who makes no effort at self-control, yoga is hard to reach. But for someone who keeps striving and uses the right means, it is achievable. Both halves matter. The first refuses to pretend that it is easy. The second refuses to let difficulty become an excuse. 'By the right means' also matters: effort without method wastes itself.
