How can I know if God Exists? - H. H. Radhanath Swami

लक्षूनियां योगी पाहाती आभास । तें दिसे आम्हांस दृष्टीपुढे ॥
कर दोन्ही कटी राहिलासे उभा । सांवळी हे प्रभा अंगकांती ॥
व्यापुनि वेगळें राहिलांसे दूरी । सकळा अंतरी निर्विकार ॥
रूप नाही रेखा नाम ही जयासी । आपुल्या मानसी शिव ध्याय ॥
अंत नाही पार वर्ण नाही थार । कुळ याति शिर हस्त पाद ॥
अचेत चेतले भक्ताचिया सुखें । आपुल्या कौतुकें तुका म्हणे॥

Yogis try hard to realize him through meditations and He is here, standing in front of us.
He is standing here with both his hands beautifully placed onto his waist. He has dark blue/black complexion .
He occupies everything that exists and is still different from everything. He is present inside everyone and is still without any shape.
He does not have any form, name etc and Lord Shiva is always meditating Him.
He does not have any beginning or end, does not have any color, caste, creed, hands or legs.
And Tuka says, such almighty Lord has taken a form, for the pleasure of His devotees and for his own Lila.
