Haripath - Sant Gnyaneshwar
सात पाच तीन दशकांचा मेळा ।
एकतत्त्वी कळा दावी हरि ॥ १ ॥
तैसे नव्हे नाम सर्व मार्गा वरिष्ठ ।
येथे काही कष्ट न लागती ॥ २ ॥
अजपा जपणे उलट प्राणाचा ।
तेथेही मनाचा निर्धारु असे ॥ ३ ॥
ज्ञानदेवा जिणे नामेविण व्यर्थ ।
रामकृष्णी पंथ क्रमीयेला ॥ ४ ॥
Others say the number is five, or three, or ten.
When Hari is realized, He reveals that, no matter what the number, as all those principles emanate from Him alone.
The name of God is not like that. It's the easiest pathway to approach to the Lord; It involves no strain or pain.
Ajapa-japa, the practice of mentally imposing the name in your inhaling and exaling breath. [Then all your breath (21,600 per day) is Nama Japa]. To pursue this practice, one needs much stamina and strength of will;
But the chanting of God's name with love is free of all such difficulties.
Jnanadev says: I'm convinced that a man lives in vain, if he does not resort to the Name. That's why I continue to extol, the chanting of the Name.
