Meditation is the key

शैवयोगवर्णनं नामैकोनचत्वारिंशोऽध्यायः

Shaiva Yoga description Chapter 39

उपमन्युरुवाच |

Upamanyu said (to Lord Krishna)

यस्मात्सौख्यं च मोक्षं च ध्यानादभयमाप्नुयात् |
तस्मात्सर्वं परित्यज्य ध्यानयुक्तो भवेन्नरः || 21 ||
नास्ति ध्यानं विना ज्ञानं नास्ति ध्यानमयोगिनः |
ध्यानं ज्ञानं च यस्यास्ति तीर्णस्तेन भवार्णवः || 22 ||

Since happiness, liberation and fearlessness are obtained by
meditation, therefore a man may give up everything (and) then become
meditation-oriented.
There is no (higher) knowledge without meditation; one who is not a
Yogi cannot meditate. One who has meditation and (higher) knowledge
has swam across the sea of the material world.
