At baseline and following thirty days, all participants completed DLST and SLCT. Results: Trāṭaka intervention showed significant change in DLST scores, increase (P-value< 0.000) in total attempted score, significant increase (P-value<0.000) in net score, significant reduction in wrongly attempted score (P-value<0.000). Significant change in SLCT scores, significant increase (P-value<0.000) in total attempted score, Similarly, significant increase (P-value<.000) in net score, significant reduction in wrongly attempted score (P-value<0.000).
