Jai Sri Ganesha,
The phenomena of nature is based with truth of action and reaction to equate the truth,
So is the truth of man who belongs to nature, it need acquired immune system to sustain against the odds of journey from the fellow beings,
In Bhakti Path of Shiva, devotees attain this feature to update self to sustain in journey,
Shiva is known for being taking poison resulted from the friction of life and let the nectar flow for the cause of spirit in journey,
May Lord bless all,
Thanks please
