તાડે ચડનારને ટેકા હાથ પહોંચે ત્યાં સુધી.

tāḍē caḍanāranē ṭēkā hātha pahōṁcē tyāṁ sudhī.

Literally: For one climbing a palmyra tree, support is only as far as the hand can reach.
What it means: External assistance can only help a person start a difficult task, but they must rely on their own strength to complete it.
