At the recent NAMA conference I loved the workshop, Role of Ojas in Building A Healthy Family from Birth to Old Age. It reminded me of the importance of ojas. And one speaker suggested a good way to increase ojas is through Loving Kindness Meditation. ( 30% off all NAMA 2022 videos through June 30!)
This form of the Loving Kindness Meditation is what I use: I sit for meditation, focusing on the love I feel towards a person or deity. When this feeling is firmly established, I let go of the object and allow the love to be inward, filling my whole body and aura as I inhale and radiating outward from my heart like moonlight, as I exhale. This inborn love never is depleted.
Try it! You may find it renewing and also ojas increasing.
