Guru das mein jo tu karm kaandi hoga toh kamaal hogi, chahe sookha peepal hi hai tu lakdi teri toh phir bhi havan mein istemaal hogi.
If you are a ritualistic person with Jupiter in the 10th, it will be amazing; even if you are a dry Peepal tree, your wood will still be used in the Havan.
This is a beautiful, poetic metaphor for people with Jupiter in the 10th house who feel useless or unsuccessful in their careers.
Dr. Sharma compares them to a dry Peepal tree ("sookha peepal"). A dry tree doesn't give fruit or shade, and society might consider it worthless. However, the wood of the Peepal tree is sacred and is always used in holy fire rituals (Havan).
The lesson? Even if you feel you haven't achieved massive worldly success, if you stay connected to your religious duties and rituals ("karm kaandi"), your life will still have immense spiritual value and purpose. You are sacred.
