असाध्य तें साध्य करितां सायास - संत तुकाराम

साधुनी बचनाग खाती तोळा तोळा । आणिकातें डोळां न पाहावे ॥१॥

साधुनी भुजंग धरितील हातीं । आणिकें कापती देखोनियां ॥२॥ असाध्य तें साध्य करितां सायास । कारण अभ्यास तुका म्हणे ॥३॥ 

 This is one of the famous motivational abhang from Sant Tukaram. It will inspire everyone, including devotees of God and non-devotees alike in their pursuits.

 साधुनी बचनाग खाती तोळा तोळा । आणिकातें डोळां न पाहावे ॥१॥

"बचनाग" is a plant found in jungles, which is poisonous, it results in acidity, vomiting and in some cases, death. Sant Tukaram says, there are people who have trained themselves and won over this plant, such that they can eat quantities of it together. However, a normal person cannot even see it.

साधुनी भुजंग धरितील हातीं । आणिकें कापती देखोनियां ॥२॥

There are some people who have learned how to handle snakes. However, a normal person trembles at seeing snakes.

असाध्य तें साध्य करितां सायास । कारण अभ्यास तुका म्हणे ॥३॥

Sant Tukaram with the above examples now says, if one really endeavors, even impossible things become possible. With consistent effort and study, one can achieve even seemingly impossible goals.

So be focused, consistent in your efforts and you'll surely achieve your goals.
