Bhagavad Gita 9.13 · Krishna
Great souls turn toward Me
महात्मानस्तु मां पार्थ दैवीं प्रकृतिमाश्रिताः।
भजन्त्यनन्यमनसो ज्ञात्वा भूतादिमव्ययम्॥
mahātmānastu māṃ pārtha daivīṃ prakṛtimāśritāḥbhajantyananyamanaso jñātvā bhūtādimavyayam
But great souls, Partha, resting in the divine nature, love Me with undivided minds, knowing Me as the undying source of all.
What it means
Krishna describes mahatmas, great souls. They rest in daivi prakriti, the divine side of nature, gentle, clear, generous. Their minds aren't split among a hundred cravings. They love Krishna wholeheartedly, knowing him as the eternal source of every being. Greatness here means a whole heart.
The story
After describing those who scatter themselves in empty hopes, Krishna turns to the opposite. Arjuna can choose which nature to rest in. The divine one is always available.
In your life
Think of someone like a beloved nurse or teacher whose whole heart is in their work. People call them great-souled. Give one thing today your whole heart.
A whole heart makes a great soul.
