The significance of a sankalpam pooja includes:

• Preserving tradition: A sankalpam is a tradition that has been passed down through generations, and its significance lies in its effort to preserve the culture and heritage. 
• Letting the lord know: Taking a sankalpam before a pooja is similar to writing “To Address” and “From Address” on a letter. It’s a way to let the lord know that you are remembering them. 
• Setting a positive intention: A sankalpam should be positive in nature. For example, instead of saying “I will not be stressed”, you can say “Peace is available to me”.
