ज्ञान

तरी परमात्मा ऐसें । जें एक वस्तु असे । ते जया दिसे । ज्ञानास्तव ॥
ते एकवांचूनि आनें । जियें भवस्वर्गादे ज्ञानें । ते अज्ञान ऐसा मने । निश्चयो केला ॥
The knowledge which lets us see/understand the परमात्मा, is the true knowledge. All other knowledge about earthly things and that about Swarga, is not true knowledge (अज्ञान).

स्वर्गा जाणे हे सांडी । भवविशयी कान झाडी । दे अध्यात्मज्ञानीं बुडी । सद्भावाची ॥
भंगलिया वाटे । शोधुनियां अव्हाटें । निघिजे जेवीं निटें । राजपंथे ॥
ज्ञानी (one who has knowledge) does not care about swarga (heaven) and earthly pleasures. With devotion, he goes for spiritual knowledge. When there are many paths of knowledge available, he finds out about all the paths and selects the best path for the purpose.

तैसे ज्ञानजातां करी । आघवेंचि एकीकडे सारी । मग मन बुद्धि मोहरी । अध्यात्मज्ञानीं ॥
म्हणे एक हेंचि आथी । येर जाणणें ते भ्रांती । ऐसी निकुरेंसी मती। मेरू होय ॥
He sets aside all other knowledge (does not care much about them),  focuses his intelligence and mind onto spiritual knowledge. He thinks that having spiritual knowledge is everything because all other forms of knowledge are like useless (like leaving ones path, unknowingly).

ए‍र्‍हवीं बोधा आलेनि ज्ञानें । जरी ज्ञेय न दिसेचि मनें । तरी ज्ञानलाभुही मने । जाहला सांता ॥
आंधळेनि हातीं दिवा । घेऊनि काय करावा ? । तैसा ज्ञान निश्चयो आघवा । वायांचि जाय ॥
जरि ज्ञानाचेनि प्रकाशें । परतत्त्वीं दिठी न पैसे । ते स्फूर्तीचि असे । अंध होउनि ॥
Anyways, if one gains spiritual knowledge and he still can not see true nature of all things, it means he never actually got this knowledge. The way giving a lamp to the blind person is of no use, in the same way knowledge of such person is useless. If he can not see the reality, it is as good as saying the person is spiritually blind.
