Shiva Purana
प्रमादो नाम योगस्य साधना नाम भावना ॥ इदं वेत्युभयाक्रान्तं विज्ञानं स्थानसंशयः ॥ ४ ॥
Blunder is the non-contemplation of the means of Yoga. Doubtfulness is the double perception—“this or this?”
english translation
pramAdo nAma yogasya sAdhanA nAma bhAvanA ॥ idaM vetyubhayAkrAntaM vijJAnaM sthAnasaMzayaH ॥ 4 ॥
