Why is the number 8 associated with Lord Krishna?

 Lord Krishna is the incarnation of lord Vishnu. He is one of the widely revered gods in Hindu pantheon. He is seen as the best lover in Vrindavan and the best strategic in the battlefield of Kurukshetra. Whether he is with his Gopis in the middle of the meadow or with his enemies in the middle of the battlefield, one thing is common - his mystic smile on his face.

Let us understand the significant of associating of number 8 with lord Krishna.

In numerology, the number 8 represents infinity and everything good in the universe which is infinite. It is the number of supplying of infinity and abundance without any lack - infinite wisdom, infinite prosperity, infinite love, infinite joy, and infinite happiness. In other words - it is the number of the completeness and unending abundance.

The number 8 have no ending and it loops back itself. No one knows where it starts and where it ends. Like number 8, no one knows what is hidden in the mystic smile of lord Krishna. Like infinity, lord Krishna cannot be understood.

There are 8 Rasas or emotions of drama (love, humor, sadness, anger, courage, fear, horror, and wonder). Lord Krishna is the master of Raslila. The science of Yoga has eight limbs, the ashtanga yoga or the eight-limbed yoga. The ashtanga yoga is the considered the complete yoga. And he is known as Yogiraj . The best form of salutation to the deity is considered the eight-fold salutation (shashtanga namakaskaram). He is that deity.

There are 8 forms of Laxmi. Laxmi is the consort of lord Vishnu. The persons who have got the blessings of these eight forms of Laxmi, he is considered a complete man. These eight forms of Laxmi are the eight Shaktis of Lord Vishnu. And in Krishna incarnation, these eight Shaktis became his eight wives. He is Pati (husband) of these eight forms. Pati means owner. That means - he is the owner of the completeness and infinity.

He is considered a complete incarnation of lord Vishnu. He is above of all the finite existence. He is above of all duality - pain or pleasure, happiness and distress, victory or defeat, love or hatred. He is the complete. He is a knower of the infinity. And the knower of the infinity, never bewildered with finite and its upheaval. His mystic smile expresses that. The number 8 is the best-suited indication of his personality.
